CVE-2026-28755  (opens in a new tab)
CWE-863  (opens in a new tab)

How to fix?

Upgrade Alpine:3.22 nginx to version 1.28.3-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream nginx package and not the nginx package as distributed by Alpine. See How to fix? for Alpine:3.22 relevant fixed versions and status.

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.
