What is CVE-2026-46401?

HAX CMS helps manage microsite universe with PHP or NodeJs backends. Versions prior to 26.0.0 suffer from an improper session termination vulnerability where authentication tokens remain valid after user logout. This allows attackers who obtain valid tokens to maintain persistent access to authenticated CMS functionality, bypassing the intended session termination mechanism and enabling unauthorized access to CMS metadata and administrative functions. Version 26.0.0 fixes the issue.
