Authentication bypass via hard-coded JWT signing key
Published Sep 1, 2022 · Updated Aug 3, 2024
Hard-coded credentials in Novel-Plus 3.6.2 allow remote attackers to forge JWTs and create arbitrary authenticated user sessions. The project configuration embeds a single JWT signing key that the authentication path uses to validate client-supplied session tokens. Possession of the published key removes the login gate, so an unauthenticated network attacker can select session claims accepted by protected functions.
