This medium-severity CVE scores 5.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 77% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
