Summary
CVE-2026-28755 affecting package nginx for versions less than 1.28.3-1
Details

NGINX Plus and NGINX Open Source have 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.  

Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
