CVE-2025-53960Network attack vector

Account takeover via password-signed JWTs

Published Dec 12, 2025 · Updated Dec 12, 2025

Weak JWT signing in Apache StreamPark 2.0.0 through 2.1.6 allows remote attackers to recover passwords or forge identity tokens. The console's JWT issuance path passes the user's password directly to HS256 as the HMAC key instead of using an independent random secret. A captured JWT enables offline password guessing; a known or recovered password permits forged tokens and complete takeover of that user's account.
