Official Description

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.
