CVE-2026-5622Network attack vector

JWT token forgery via hard-coded signing key

Published Apr 6, 2026 · Updated Apr 6, 2026

Hard-coded cryptographic key use in Huly Platform 0.7.382 allows remote attackers to forge JWT tokens through the token handler. The token.ts handler uses the literal SERVER_SECRET value secret as the shared JWT signing key without rejecting the documented default. The affected deployment must retain that default key; forged tokens compromise authentication integrity, with no reported data disclosure or service interruption.
