CWE-22 — Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

This CVE was published Jul 03, 2026 and is one of 4 known issues for this plugin.

What to do

Update, patch or deactivate.

Update AR for WordPress to a release after 8.40, or disable and remove it until a fixed version is available.

A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.

Source record

Technical description

The AR for WordPress plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 8.40 via the 'file' parameter parameter. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information. Exploitation requires an attacker to first obtain a valid nonce and secure nonce via the publicly accessible ar_get_fresh_nonce and ar_process_user_image nopriv AJAX handlers, and to reproduce the encryption key locally — both steps are fully achievable by an unauthenticated attacker on any default free or unlicensed installation where ar_licence_key is unset.
