Aug 5, 2026Custom Fields: Does not validate a user-supplied file path before deletionCVE-2026-16940 · fixed in 1.5.1 · reported by WPScanCritical 10
The Custom Fields WordPress plugin before 1.5.1 does not validate a user-supplied file path before deletion, allowing unauthenticated users to delete arbitrary files on the server (such as wp-config.php), which can lead to a full site takeover.
Versions are matched against the affected ranges published with each record. A plugin can ship a fix under its own numbering, so if something looks off, check the linked record. Want the whole site checked at once? Run the free website check.
