Technical details
An improper authentication vulnerability exists in Kavita due to flawed token validation logic. The root cause involves insufficient verification of data authenticity and incorrect comparisons during the authentication process (CWE-287, CWE-345, CWE-697). A remote, unauthenticated attacker can exploit this by requesting a JSON Web Token (JWT) for any valid username, including administrative accounts. Successful exploitation results in complete account takeover and full access to the application's API and management features. The vulnerability is addressed in version 0.9.0.2.
