This CVE was published Jul 14, 2026 and is one of 26 known issues for this plugin.

Update, patch or deactivate.

Update AI Engine to 3.5.5 or later, or disable and remove it until a fixed version is available.

Technical description

The AI Engine WordPress plugin before 3.5.5 does not sanitize a user-supplied filename before using it to write a downloaded file, allowing authenticated users with editor-level access to write attacker-controlled bytes to an arbitrary location on the server via path traversal.
