Dataease CVE-2026-55633

DataEase versions prior to 2.10.24 contain a remote code execution vulnerability allowing authenticated users to bypass security hardening and execute arbitrary code on affected servers. Organizations running vulnerable versions face potential unauthorized system access, data exfiltration, and operational disruption. Immediate access restrictions and endpoint controls are required pending official patch availability.

24 hours: Inventory all DataEase deployments and document current versions; restrict font management privileges to essential administrative accounts; disable FontManage functionality if operationally feasible. 7 days: Implement network segmentation limiting DataEase server access to trusted networks; deploy Web Application Firewall rules blocking .ttf files with embedded ZIP protocol signatures; enable audit logging on file-upload and database-access endpoints. 30 days: Monitor GHSA-8x36-774q-pwqg and DataEase releases for official patch; prepare and test upgrade to version 2.10.24 or later; execute patch deployment with change management controls.

No vendor-released patch identified at time of analysis. Interim mitigations: (1) Restrict or disable FontManage.saveFile endpoint if not required for operations; (2) Apply network segmentation to isolate DataEase infrastructure; (3) Deploy WAF rules to block suspicious .ttf uploads with ZIP protocol artifacts; (4) Enforce least-privilege account access for font management functions; (5) Enable comprehensive audit logging for all file uploads and H2 database interactions; (6) Temporarily suspend font file upload capabilities if compensating controls cannot be fully implemented.
