Rodauth before 2.47.0 contains an authentication bypass vulnerability in the jwtrefresh route that issues new JWT access tokens without requiring a refresh token. Attackers can present an access token to the refresh route via non-POST methods to obtain a new valid access token, enabling indefinite account access with temporary token possession.

Rodauth before 2.47.0 contains a time-based one-time password reuse vulnerability in the otp feature that fails to track the last accepted code timestamp. Attackers who observe a valid TOTP code can replay it during the drift window to bypass the second authentication factor.

Rodauth before 2.47.0 contains a cross-site request forgery protection bypass vulnerability in the JSON request content type validation. Attackers can craft cross-origin form posts with content types containing application/json substrings to bypass CSRF token validation and force victims to authenticate to attacker-controlled accounts.

Rodauth before 2.46.0 contains an authentication bypass vulnerability in the webauthnlogin route that allows logged-in users to authenticate as any other account. Attackers can exploit improper account resolution logic that falls back to session account identifiers instead of validating the credential binding to complete authentication as arbitrary users.

Rodauth before 2.47.0 fails to validate protocol-relative return-to paths in confirmpassword, loginreturntorequestedlocation, and twofactorauthreturntorequestedlocation features. Attackers can craft paths with leading double slashes that browsers resolve as protocol-relative URLs, redirecting authenticated users to attacker-controlled sites after login or password confirmation.
