CVE-2026-9094Network attack vector

Cross-organization privilege escalation via unbound token exchange

Published May 28, 2026 · Updated May 28, 2026

Incorrect authorization in Casdoor 2.362.0 and earlier allows remote attackers to escalate privileges across organizations via token exchange. GetTokenExchangeToken in object/token_oauth.go validates a subject JWT with the target application's certificate without confirming its issuer or binding its audience to the requesting client. Possession of a JWT issued for one application is sufficient to obtain a token beyond its intended organizational boundary.
