Gitea · Gitea
Gitea's OAuth2 and OpenID Connect sign-in paths fail to enforce a WebAuthn challenge for accounts whose only configured second factor is WebAuthn, so the passkey check applied during password login is skipped. An attacker able to authenticate through the affected external identity flow can obtain a full session without passkey verification, and one affected path can also persist an external identity link that extends the compromise beyond that session; accounts with TOTP configured are not part of this scenario.
Gitea's OAuth2 and OpenID Connect sign-in paths do not require a WebAuthn challenge when WebAuthn is the account's only configured second factor. A party able to authenticate through the affected external identity flow can obtain a full session without the passkey verification enforced during password login. One affected path can also persist an external identity link, extending the compromise beyond the initial session; accounts with TOTP configured are outside the reported WebAuthn-only scenario.
