CVE-2026-5622 hcengineering CVE debrief

Who should care

Users of hcengineering Huly Platform 0.7.382, particularly those responsible for vulnerability management, security teams, and platform operators, should assess the risk of this vulnerability and apply patches or mitigations as available. This involves reviewing system configurations, ensuring that the JWT Token Handler is properly secured, and monitoring for any suspicious activity related to the manipulation of SERVER_SECRET. Additionally, affected teams should prioritize patching or updating the vulnerable component to prevent potential remote attacks.

Technical summary

The vulnerability is in the JWT Token Handler component of hcengineering Huly Platform 0.7.382, specifically in the file foundations/core/packages/token/src/token.ts. The issue involves the use of a hard-coded cryptographic key when manipulating the SERVER_SECRET argument with the input 'secret'. The attack vector is remote, with high complexity and difficult exploitation. This could allow attackers to compromise the security of the platform by exploiting the hard-coded key. Users should review the configuration of the JWT Token Handler to ensure it is not exposed to remote attackers and consider implementing compensating controls such as additional authentication or access controls.

Defensive priority

Apply patches or updates from the vendor as soon as available. In the absence of patches, review the configuration of the JWT Token Handler to ensure that it is not exposed to remote attackers. Monitor for any suspicious activity related to the manipulation of SERVER_SECRET.

Recommended defensive actions
