Unauthenticated command execution via unsigned enterprise JWTs
Published Jul 15, 2026 · Updated Jul 15, 2026
Authentication bypass in FIT2CLOUD DataEase before 2.10.23 allows remote attackers to execute commands through forged enterprise tokens. TokenFilter passes X-DE-TOKEN to TokenUtils.validate, which checks only length before userBOByToken decodes attacker-chosen uid and oid claims without verifying the JWT signature. The chain requires licenseValid=true; an accepted identity can supply Redshift loggerFile parameters that write a scheduled script, resulting in command execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
