| CVE-2021-40150 | The web server of the E1 Zoom camera through 3.0.0.716 discloses its configuration via the /conf/ directory that is mapped to a publicly accessible path. In this way an attacker can download the entire NGINX/FastCGI configurations by querying the /conf/nginx.conf or /conf/fastcgi.conf URI. | high | |
| CVE-2026-45560 | Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. In versions 8.2.6.4 and prior, wrap_line (app/modules/common/common.py:181-186) and highlight_word (app/modules/common/common.py:188-192) build raw HTML by string concatenation with no escaping. The frontend (app/static/js/script.js, log-viewer paths) uses .html(data) / .append(data) to inject the response body. Anyone able to write a line into a managed HAProxy/Nginx access log (i.e. anyone who can send an HTTP request to the public LB) can land an <svg/onload=…> payload that executes when a Roxy-WI admin opens the log viewer. At time of publication, there are no publicly available patches. | medium | |
| CVE-2020-5863 | In NGINX Controller versions prior to 3.2.0, an unauthenticated attacker with network access to the Controller API can create unprivileged user accounts. The user which is created is only able to upload a new license to the system but cannot view or modify any other components of the system. | high | |
| CVE-2020-5895 | On NGINX Controller versions 3.1.0-3.3.0, AVRD uses world-readable and world-writable permissions on its socket, which allows processes or users on the local system to write arbitrary data into the socket.

| CVE-2026-42926 | When NGINX Open Source is configured to proxy HTTP/2 traffic by setting proxy_http_version to 2, and also uses proxy_set_body, an attacker may be able to inject frame headers and payload bytes to the upstream peer. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. | medium | |
| CVE-2025-34203 | Vasion Print (formerly PrinterLogic) Virtual Appliance Host versions prior to 22.0.1002 and Application versions prior to 20.0.2614 (VA and SaaS deployments) contain multiple Docker containers that include outdated, end-of-life, unsupported, or otherwise vulnerable third-party components (examples: Nginx 1.17.x, OpenSSL 1.1.1d, various EOL Alpine/Debian/Ubuntu base images, and EOL Laravel/PHP libraries). These components are present across many container images and increase the product's attack surface, enabling exploitation chains when leveraged by an attacker. Multiple distinct EOL versions and unpatched libraries across containers; Nginx binaries date from 2019 in several images and Laravel versions observed include EOL releases (for example Laravel 5.5.x, 5.7.x, 5.8.x). This vulnerability has been identified by the vendor as: V-2024-014 — Outdated Dependencies. | critical | |
| CVE-2023-25804 | Roxy-WI is a Web interface for managing Haproxy, Nginx, Apache, and Keepalived servers. Versions prior to 6.3.5.0 have a limited path traversal vulnerability.

| CVE-2025-11379 | The WebP Express plugin for WordPress is vulnerable to information exposure via config files in all versions up to, and including, 0.25.9. This is due to the plugin not properly randomizing the name of the config file to prevent direct access on NGINX. This makes it possible for unauthenticated attackers to extract configuration data. | medium | |
| CVE-2023-36809 | Kiwi TCMS, an open source test management system allows users to upload attachments to test plans, test cases, etc. Versions of Kiwi TCMS prior to 12.5 had introduced changes which were meant to serve all uploaded files as plain text in order to prevent browsers from executing potentially dangerous files when such files are accessed directly. The previous Nginx configuration was incorrect allowing certain browsers like Firefox to ignore the `Content-Type: text/plain` header on some occasions thus allowing potentially dangerous scripts to be executed. Additionally, file upload validators and parts of the HTML rendering code had been found to require additional sanitation and improvements. Version 12.5 fixes this vulnerability with updated Nginx content type configuration, improved file upload validation code to prevent more potentially dangerous uploads, and Sanitization of test plan names used in the `tree_view_html()` function. | medium | |
| CVE-2024-1076 | The SSL Zen WordPress plugin before 4.6.0 does not properly prevent directory listing of the private keys folder, as it only relies on the use of .htaccess to prevent visitors from accessing the site's generated private keys, which allows an attacker to read them if the site runs on a server who doesn't support .htaccess files, like NGINX. | medium | |
| CVE-2026-54652 | Frigate is an open source network video recorder. In version 0.17.1, the GET /api/logs/{service} endpoint allows any authenticated user including the viewer role to download Frigate and nginx logs, exposing auto-generated admin passwords and camera credentials logged in request query strings and enabling viewer-to-admin privilege escalation. A fixed release has not been identified. | high | |
| CVE-2020-5899 | In NGINX Controller 3.0.0-3.4.0, recovery code required to change a user's password is transmitted and stored in the database in plain text, which allows an attacker who can intercept the database connection or have read access to the database, to request a password reset using the email address of another registered user then retrieve the recovery code. | high | |
| CVE-2022-31125 | Roxy-wi is an open source web interface for managing Haproxy, Nginx, Apache and Keepalived servers. A vulnerability in Roxy-wi allows a remote, unauthenticated attacker to bypass authentication and access admin functionality by sending a specially crafted HTTP request. This affects Roxywi versions before 6.1.1.0. Users are advised to upgrade. There are no known workarounds for this issue. | critical | |
| CVE-2021-32637 | Authelia is a a single sign-on multi-factor portal for web apps. This affects uses who are using nginx ngx_http_auth_request_module with Authelia, it allows a malicious individual who crafts a malformed HTTP request to bypass the authentication mechanism. It additionally could theoretically affect other proxy servers, but all of the ones we officially support except nginx do not allow malformed URI paths. The problem is rectified entirely in v4.29.3. As this patch is relatively straightforward we can back port this to any version upon request. Alternatively we are supplying a git patch to 4.25.1 which should be relatively straightforward to apply to any version, the git patches for specific versions can be found in the references. The most relevant workaround is upgrading. You can also add a block which fails requests that contains a malformed URI in the internal location block. | critical | |
| CVE-2022-31126 | Roxy-wi is an open source web interface for managing Haproxy, Nginx, Apache and Keepalived servers. A vulnerability in Roxy-wi allows a remote, unauthenticated attacker to code execution by sending a specially crafted HTTP request to /app/options.py file. This affects Roxy-wi versions before 6.1.1.0. Users are advised to upgrade. There are no known workarounds for this issue. | critical | |
| CVE-2024-10318 | A session fixation issue was discovered in the NGINX OpenID Connect reference implementation, where a nonce was not checked at login time. This flaw allows an attacker to fix a victim's session to an attacker-controlled account. As a result, although the attacker cannot log in as the victim, they can force the session to associate it with the attacker-controlled account, leading to potential misuse of the victim's session. | medium | |
| CVE-2026-22265 | Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. Prior to 8.2.8.2, command injection vulnerability exists in the log viewing functionality that allows authenticated users to execute arbitrary system commands. The vulnerability is in app/modules/roxywi/logs.py line 87, where the grep parameter is used twice - once sanitized and once raw. This vulnerability is fixed in 8.2.8.2. | high | |
| CVE-2026-27633 | TinyWeb is a web server (HTTP, HTTPS) written in Delphi for Win32. Versions prior to version 2.02 have a Denial of Service (DoS) vulnerability via memory exhaustion. Unauthenticated remote attackers can send an HTTP POST request to the server with an exceptionally large `Content-Length` header (e.g., `2147483647`). The server continuously allocates memory for the request body (`EntityBody`) while streaming the payload without enforcing any maximum limit, leading to all available memory being consumed and causing the server to crash. Anyone hosting services using TinyWeb is impacted. Version 2.02 fixes the issue. The patch introduces a `CMaxEntityBodySize` limit (set to 10MB) for the maximum size of accepted payloads. As a temporary workaround if upgrading is not immediately possible, consider placing the server behind a Web Application Firewall (WAF) or reverse proxy (like nginx or Cloudflare) configured to explicitly limit the maximum allowed HTTP request body size (e.g., `client_max_body_size` in nginx). | high | |
| CVE-2022-31137 | Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. Versions prior to 6.1.1.0 are subject to a remote code execution vulnerability. System commands can be run remotely via the subprocess_execute function without processing the inputs received from the user in the /app/options.py file. Attackers need not be authenticated to exploit this vulnerability. Users are advised to upgrade. There are no known workarounds for this vulnerability. | critical | |
| CVE-2026-52761 | ModSecurity is an open source, cross platform web application firewall (WAF) engine for Apache, IIS and Nginx. From 3.0.0 through 3.0.15, the t:utf8toUnicode transformation in src/actions/transformations/utf8_to_unicode.cc produces wrong output on i386 architecture because snprintf uses sizeof on a char pointer rather than the length of the unicode buffer, allowing rules that use this transformation to be bypassed on i386 architecture. This issue is fixed in version 3.0.16. | medium | |
| CVE-2020-11724 | An issue was discovered in OpenResty before 1.15.8.4. ngx_http_lua_subrequest.c allows HTTP request smuggling, as demonstrated by the ngx.location.capture API. | high | |
| CVE-2024-24562 | vantage6-UI is the official user interface for the vantage6 server. In affected versions a number of security headers are not set. This issue has been addressed in commit `68dfa6614` which is expected to be included in future releases. Users are advised to upgrade when a new release is made. While an upgrade path is not available users may modify the docker image build to insert the headers into nginx. | medium | |
| CVE-2026-5524 | The Divi Form Builder plugin for WordPress is vulnerable to Arbitrary File Upload leading to Remote Code Execution in all versions up to and including 5.1.8. This is due to insufficient file extension validation in the do_image_upload() function where user-supplied input from the acceptFileTypes POST parameter is directly interpolated into a regular expression used to validate uploaded files. Attackers can specify PHP-executable extensions such as .phtml, .phar, .php5, or .php7 to bypass the plugin's .htaccess protection which only blocks .php files specifically. Additionally, on Nginx-based servers, the .htaccess protection is completely ineffective as Nginx does not process .htaccess files. This makes it possible for unauthenticated attackers (who can obtain a nonce from any public page containing a form) to upload executable PHP files to the publicly accessible /wp-content/uploads/de_fb_uploads/ directory and achieve Remote Code Execution by accessing the uploaded file via HTTP. The vulnerability was partially patched in version 5.1.3. | critical | |
| CVE-2025-54571 | ModSecurity is an open source, cross platform web application firewall (WAF) engine for Apache, IIS and Nginx. In versions 2.9.11 and below, an attacker can override the HTTP response’s Content-Type, which could lead to several issues depending on the HTTP scenario. For example, we have demonstrated the potential for XSS and arbitrary script source code disclosure in the latest version of mod_security2. This issue is fixed in version 2.9.12. | medium | |
| CVE-2026-33078 | Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. Versions prior to 8.2.6.4 have a SQL injection vulnerability in the haproxy_section_save function in app/routes/config/routes.py. The server_ip parameter, sourced from the URL path, is passed unsanitized through multiple function calls and ultimately interpolated into a SQL query string using Python string formatting, allowing attackers to execute arbitrary SQL commands. Version 8.2.6.4 fixes the issue. | critical | |
| CVE-2021-23050 | On BIG-IP Advanced WAF and BIG-IP ASM version 16.0.x before 16.0.1.2 and 15.1.x before 15.1.3 and NGINX App Protect on all versions before 3.5.0, when a cross-site request forgery (CSRF)-enabled policy is configured on a virtual server, an undisclosed HTML response may cause the bd process to terminate. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. | high | |
| CVE-2025-23001 | A Host header injection vulnerability exists in CTFd 3.7.5, due to the application failing to properly validate or sanitize the Host header. An attacker can manipulate the Host header in HTTP requests, which may lead to phishing attacks, reset password, or cache poisoning. NOTE: the Supplier's position is that the end user is supposed to edit the NGINX configuration template to set server_name (with this setting, Host header injection cannot occur). | medium | |
| CVE-2026-3229 | An integer overflow vulnerability existed in the static function wolfssl_add_to_chain, that caused heap corruption when certificate data was written out of bounds of an insufficiently sized certificate buffer. wolfssl_add_to_chain is called by these API: wolfSSL_CTX_add_extra_chain_cert, wolfSSL_CTX_add1_chain_cert, wolfSSL_add0_chain_cert. These API are enabled for 3rd party compatibility features: enable-opensslall, enable-opensslextra, enable-lighty, enable-stunnel, enable-nginx, enable-haproxy. This issue is not remotely exploitable, and would require that the application context loading certificates is compromised. | low | |
| CVE-2024-41668 | The cBioPortal for Cancer Genomics provides visualization, analysis, and download of large-scale cancer genomics data sets. When running a publicly exposed proxy endpoint without authentication, cBioPortal could allow someone to perform a Server Side Request Forgery (SSRF) attack. Logged in users could do the same on private instances. A fix has been released in version 6.0.12. As a workaround, one might be able to disable `/proxy` endpoint entirely via, for example, nginx. | high | |
| CVE-2026-9508 | Incorrect permission settings on a critical resource in Suprema BioStar 2 (versions 2.9.3 through 2.9.11) that allow backup files to be publicly exposed when the administrator configures their path within the NGINX webroot. This vulnerability allows an attacker with network access to directly download backup ZIP files via ‘http(s)://[server]/download/…’ without requiring authentication. This exposes highly sensitive information that can lead to server impersonation, unauthorized access to databases, and lateral movement. | critical | |
| CVE-2018-12029 | A race condition in the nginx module in Phusion Passenger 3.x through 5.x before 5.3.2 allows local escalation of privileges when a non-standard passenger_instance_registry_dir with insufficiently strict permissions is configured. Replacing a file with a symlink after the file was created, but before it was chowned, leads to the target of the link being chowned via the path. Targeting sensitive files such as root's crontab file allows privilege escalation. | high | |
| CVE-2021-42717 | ModSecurity 3.x through 3.0.5 mishandles excessively nested JSON objects. Crafted JSON objects with nesting tens-of-thousands deep could result in the web server being unable to service legitimate requests. Even a moderately large (e.g., 300KB) HTTP request can occupy one of the limited NGINX worker processes for minutes and consume almost all of the available CPU on the machine. Modsecurity 2 is similarly vulnerable: the affected versions include 2.8.0 through 2.9.4. | high | |
| CVE-2026-27811 | Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. Prior to version 8.2.6.3, a command injection vulnerability exists in the `/config/compare/<service>/<server_ip>/show` endpoint, allowed authenticated users to execute arbitrary system commands on the app host. The vulnerability exists in `app/modules/config/config.py` on line 362, where user input is directly formatted in the template string that is eventually executed. Version 8.2.6.3 fixes the issue. | high | |
| CVE-2026-45561 | Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. In versions 8.2.6.4 and prior, the /smon/agent/{version,uptime,status,checks}/<server_ip> family of routes takes the URL path component verbatim into requests.get(f'http://{server_ip}:{agent_port}/...'). The path component is constrained only by Flask's default URL converter, which permits any value (including IPv4 literals like 169.254.169.254, RFC1918 ranges, and 127.0.0.1). At time of publication, there are no publicly available patches. | medium | |
| CVE-2026-45563 | Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. In versions 8.2.6.4 and prior, GET /history/<service>/<server_ip> re-uses the server_ip path parameter as a user-id when service == 'user', with no authorization check. Any authenticated user — even a guest in an unrelated group — can list any other user's full action audit trail (server IPs touched, configs deployed, services restarted). At time of publication, there are no publicly available patches. | medium | |
| CVE-2025-47947 | ModSecurity is an open source, cross platform web application firewall (WAF) engine for Apache, IIS and Nginx. Versions up to and including 2.9.8 are vulnerable to denial of service in one special case (in stable released versions): when the payload's content type is `application/json`, and there is at least one rule which does a `sanitiseMatchedBytes` action. A patch is available at pull request 3389 and expected to be part of version 2.9.9. No known workarounds are available. | high | |
| CVE-2026-45556 | Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. In versions 8.2.6.4 and prior, POST /waf/<service>/<server_ip>/rule/<rule_id>/save accepts a config_file_name form field that is passed straight through to config_mod.master_slave_upload_and_restart(...) as the destination path. The validation chain (_replace_config_path_to_correct → check_is_conf) only requires the path to contain a hard-coded service substring (nginx/haproxy/apache2/httpd/keepalived) and the substring conf or cfg, and to not contain ... The encoded-slash substitution 92 → / is applied before the substring check, so the attacker can build any absolute path anywhere on the LB filesystem as long as it satisfies those substring constraints. The body of the WAF rule (config form field) is written verbatim to that path. By choosing a filename like 92etc92cron.d92nginx_cfg_evil (resolving to /etc/cron.d/nginx_cfg_evil), an attacker drops a cron entry on the load balancer with attacker-controlled content. Cron parses the file on its next scan, executing the embedded job as root — full RCE on every load balancer the caller's group manages. At time of publication, there are no publicly available patches. | critical | |
| CVE-2023-44388 | Discourse is an open source platform for community discussion. A malicious request can cause production log files to quickly fill up and thus result in the server running out of disk space. This problem has been patched in the 3.1.1 stable and 3.2.0.beta2 versions of Discourse. It is possible to temporarily work around this problem by reducing the `client_max_body_size nginx directive`. `client_max_body_size` will limit the size of uploads that can be uploaded directly to the server. | high | |
| CVE-2025-52891 | ModSecurity is an open source, cross platform web application firewall (WAF) engine for Apache, IIS and Nginx. In versions 2.9.8 to before 2.9.11, an empty XML tag can cause a segmentation fault. If SecParseXmlIntoArgs is set to On or OnlyArgs, and the request type is application/xml, and at least one XML tag is empty (eg <foo></foo>), then a segmentation fault occurs. This issue has been patched in version 2.9.11. A workaround involves setting SecParseXmlIntoArgs to Off. | medium | |
