Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Prior to 6.4.40, 7.4.12, and 8.0.12, OidcTokenHandler::verifyClaims() registered audience (aud), issuer (iss), and expiry (exp) checkers but did not pass the mandatory claims list to ClaimCheckerManager::check(), so a validly signed JWT that omitted those claims could pass verification. This issue is fixed in versions 6.4.40, 7.4.12, and 8.0.12.

The remote Debian 13 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-6312 advisory.

    Multiple vulnerabilities have been found in the Symfony PHP framework     which could lead to a bypass of security controls, cross-site scripting,     denial of service, SQL injection, email header injection, information     disclosure or code execution via PHP object deserialization.

    For the stable distribution (trixie), these problems have been fixed in     version 6.4.41+dfsg-0+deb13u1.

    We recommend that you upgrade your symfony packages.
