This critical-severity CVE scores 9.8 under NVD CVSS v3. EPSS exploit probability: 2.6%, top 16% 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).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Lack of authentication or validation in motor_load_more, motor_gallery_load_more, motor_quick_view and motor_project_quick_view AJAX handlers of the Motor WordPress theme before 3.1.0 allows an unauthenticated attacker access to arbitrary files in the server file system, and to execute arbitrary php scripts found on the server file system. We found no vulnerability for uploading files with this theme, so any scripts to be executed must already be on the server file system.
