    OOB Read via Integer Overflow on libsoup through libsoup/websocket/soup-websocket-connection.c via     process_frame() leads to Undefined Behavior (CVE-2026-0716)

    A flaw was found in libsoup, an HTTP client library. This vulnerability, known as CRLF (Carriage Return     Line Feed) Injection, occurs when an HTTP proxy is configured and the library improperly handles URL-     decoded input used to create the Host header. A remote attacker can exploit this by providing a specially     crafted URL containing CRLF sequences, allowing them to inject additional HTTP headers or complete HTTP     request bodies. This can lead to unintended or unauthorized HTTP requests being forwarded by the proxy,     potentially impacting downstream services. (CVE-2026-1467)

    A flaw was found in SoupServer. This HTTP request smuggling vulnerability occurs because SoupServer     improperly handles requests that combine Transfer-Encoding: chunked and Connection: keep-alive headers. A     remote, unauthenticated client can exploit this by sending specially crafted requests, causing SoupServer     to fail to close the connection as required by RFC 9112. This allows the attacker to smuggle additional     requests over the persistent connection, leading to unintended request processing and potential denial-of-     service (DoS) conditions. (CVE-2026-1760)

    A flaw was found in libsoup. This stack-based buffer overflow vulnerability occurs during the parsing of     multipart HTTP responses due to an incorrect length calculation. A remote attacker can exploit this by     sending a specially crafted multipart HTTP response, which can lead to memory corruption. This issue may     result in application crashes or arbitrary code execution in applications that process untrusted server     responses, and it does not require authentication or user interaction. (CVE-2026-1761)

    A flaw was found in libsoup, an HTTP client/server library. This HTTP Request Smuggling vulnerability     arises from non-RFC-compliant parsing in the soup_filter_input_stream_read_line() logic, where libsoup     accepts malformed chunk headers, such as lone line feed (LF) characters instead of the required carriage     return and line feed (CRLF). A remote attacker can exploit this without authentication or user interaction     by sending specially crafted chunked requests. This allows libsoup to parse and process multiple HTTP     requests from a single network message, potentially leading to information disclosure. (CVE-2026-1801)

    Denial of Service via use-after-free in SoupServer during TLS handshake (CVE-2026-2436)

    libsoup includes an embedded HTTP/1 server. When a server sits behind a proxy / load balancer, it's     critical that every hop agrees on how request bodies are framed.In the affected code path, libsoup     accepted HTTP/1 requests with ambiguous body framing:

    multiple Content-Length headers (CL.CL)

    Transfer-Encoding: chunked together with Content-Length (TE+CL)

    Different intermediaries pick different framing rules in these cases. If a front-end and back-end     disagree, an attacker can desynchronize the connection and smuggle an extra request through the chain.
    Depending on deployment, this can lead to routing/ACL bypass, cache poisoning, or reaching internal-only     endpoints. (CVE-2026-2708)

    A flaw was found in libsoup. When establishing HTTPS tunnels through a configured HTTP proxy, sensitive     session cookies are transmitted in cleartext within the initial HTTP CONNECT request. A network-positioned     attacker or a malicious HTTP proxy can intercept these cookies, leading to potential session hijacking or     user impersonation. (CVE-2026-5119)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A request smuggling vulnerability exists in libsoup's HTTP/1 header parsing logic. The     soup_message_headers_append_common() function in libsoup/soup-message-headers.c unconditionally appends     each header value without validating for duplicate or conflicting Content-Length fields. This allows an     attacker to send HTTP requests containing multiple Content-Length headers with differing values.
    (CVE-2026-2708)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2026:0274 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2026-2708:
    A request smuggling vulnerability exists in libsoup's HTTP/1 header parsing logic. The     soup_message_headers_append_common() function in libsoup/soup-message-headers.c unconditionally appends     each header value without validating for duplicate or conflicting Content-Length fields. This allows an     attacker to send HTTP requests containing multiple Content-Length headers with differing values.

    CVE-2025-14523:
    A flaw in libsoups HTTP header handling allows multiple Host: headers in a request and returns the last     occurrence for server-side processing. Common front proxies often honor the first Host: header, so this     mismatch can cause vhost confusion where a proxy routes a request to one backend but the backend     interprets it as destined for another host. This discrepancy enables request-smuggling style attacks,     cache poisoning, or bypassing host-based access controls when an attacker supplies duplicate Host headers.
