Instead, the authentication service authenticates every valid frontend user from the user lookup chain, where the  frontend user field \u201ctx_oidc\u201d is not empty.\n\nIn scenarios, where either ext:felogin is active or where `$GLOBALS[\u0027TYPO3_CONF_VARS\u0027][\u2018FE\u2019][\u2018checkFeUserPid\u2019]` is disabled, an attacker can login to OpenID Connect frontend user accounts by providing a valid username and any password.
