CVE-2025-54947Network attack vector

Unauthenticated data disclosure via fixed JWT key

Published Dec 12, 2025 · Updated Dec 12, 2025

Hard-coded cryptographic key use in Apache StreamPark 2.0.0 through 2.1.6 allows remote attackers to decrypt protected data. JWTFilter decrypts bearer tokens with the fixed key in EncryptUtils instead of an installation-specific secret. No account or user interaction is required; recovery of the embedded key enables disclosure or forgery of token-protected information.
