Unauthorized access via overlong JWT expiry
Published Jan 19, 2026 · Updated Jan 19, 2026
Insufficient session expiration in HCL AION 2 allows remote authenticated users to retain unauthorized access through compromised JWTs. HCL has not disclosed the token-issuing component, configured lifetime, or validation path responsible for the excessive expiry. Exploitation requires a valid high-privilege token and user interaction; the documented consequence is unauthorized integrity impact, not data disclosure or service interruption.
