CVE-2026-9097CVE-2026-9097
Critical 9.8
In plain English
A critical-severity security flaw in Casdoor from Casdoor. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.4% (higher than 35% of all known vulnerabilities).
Official description
Casdoor versions 2.362.0 and earlier do not verify that a JWT used for token exchange is still active. The GetTokenExchangeToken() function in object/token_oauth.go validates the JWT signature and parses its claims, but never queries the Token table to verify whether the subject token has been revoked or invalidated. Because the revocation check is entirely absent, administrators are unable to terminate active sessions or revoke compromised tokens.
