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.

Affected: Packagist: symfony/security-http, Packagist: symfony/symfony

### Description

`OidcTokenHandler` is Symfony's built-in access-token handler for OpenID Connect: it validates a bearer JWT and returns the authenticated user identity. It delegates claim validation to the `web-token/jwt-checker` library's `ClaimCheckerManager`.

`OidcTokenHandler::verifyClaims()` registers audience (`aud`), issuer (`iss`), and expiry (`exp`) checkers, but never passes the `$mandatoryClaims` argument to `ClaimCheckerManager::check()`. That method only validates claims that are *present* in the token: a checker for an absent claim is silently skipped. A validly-signed JWT that simply **omits** `aud`, `iss`, and `exp` therefore passes verification.

### Resolution

The `OidcTokenHandler` now calls the `ClaimCheckerManager` with the list of mandatory claims so that tokens missing `aud`, `iss`, or `exp` are rejected.

The patch for this issue is available [here](https://github.com/symfony/symfony/commit/6b717aaac21b7e96798448d14c4355ea87690b3d) for branch 6.4.

### Credits

Symfony would like to thank Claude Mythos Preview (via Project Glasswing) for reporting the issue and providing the fix.
