Synopsis
Nginx < 1.28.3 Multiple VulnerabilitiesDescription
According to its Server response header, the installed version of nginx is prior to 1.28.3 or 1.29.x prior to 1.29.7. It is, therefore, affected by the following issues :- A vulnerability in the ngx_http_dav_module module that might allow an attacker to trigger a buffer overflow to the NGINX worker process. (CVE-2026-27654)
- A vulnerability in the ngx_http_mp4_module module, which might allow an attacker to over-read or over-write NGINX worker memory resulting in its termination. (CVE-2026-27784)
- A vulnerability in the ngx_http_mp4_module module, which might allow an attacker to trigger a buffer over-read or over-write to the NGINX worker memory resulting in its termination or possibly code execution, using a specially crafted MP4 file. (CVE-2026-32647)
- When the ngx_mail_auth_http_module module is enabled on NGINX Plus or NGINX Open Source, undisclosed requests can cause worker processes to terminate. (CVE-2026-27651)
- NGINX Plus and NGINX Open Source have a vulnerability in the ngx_mail_smtp_module module due to the improper handling of CRLF sequences in DNS responses. (CVE-2026-28753)
- A vulnerability in the ngx_stream_ssl_module module due to the improper handling of revoked certificates when configured with the ssl_verify_client on and ssl_ocsp on directives, allowing the TLS handshake to succeed even after an OCSP check identifies the certificate as revoked. (CVE-2026-28755)
Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Upgrade to nginx version 1.28.3 or later.See Also
