CVE-2026-73278 - Gitea WebAuthn bypass during OAuth and OIDC sign-in
CVE ID :CVE-2026-73278
Published : Oct. 6, 2026, 7:33 p.m. | 12 minutes ago
Description :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.
Severity: 0.0 | NA
