CVE-2026-90942
CriticalCVSS 9.6Summary
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.
Risk Assessment
An attacker can impersonate any user, including a global administrator, leading to full compromise of the authentication system.
Recommendation
Update Casdoor to a patched version, immediately rotate the exposed private key, and invalidate all issued JWT tokens.
