Critical (9.3). EPSS 0.3% chance of exploitation in the next 30 days.
Casdoor through 4.4.0 fails to properly mask the instance-wide built-in certificate private key in /api/get-certs and /api/get-cert endpoints, allowing organization administrators to retrieve it. Attackers can use the exposed private key to forge JWT tokens for any user in any organization, including global administrators.
