Details

Rodauth before 2.47.0 contains an authentication bypass vulnerability in the jwt_refresh 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.
