What is CVE-2026-9094?

Versions of Casdoor up to 2.362.0 have a security flaw in the GetTokenExchangeToken function located in object/token_oauth.go. The function improperly validates JWT signatures, failing to confirm whether the user's token belongs to the same organization as the target application. This oversight allows for potential privilege escalation, enabling attackers to exploit organizational boundaries and gain unauthorized access to sensitive resources.

Affected Version(s)

Casdoor 0 <= 2.362.0
