CVE-2026-14352
HighCVSS 7.5Summary
The AR for WooCommerce plugin for WordPress up to version 8.40 is vulnerable to Directory Traversal via the 'file' parameter. Unauthenticated attackers can read arbitrary files on the server, including sensitive information, because three access controls fail: nonces are generated without authentication, the AES-256-CBC encryption key is predictable (derived from 'ar_licence_key' option, which defaults to false), and the Referer check is easily bypassed.
Risk Assessment
The risk involves potential exposure of sensitive information such as configuration files, credentials, or API keys, which could lead to further attacks on the WordPress infrastructure.
Recommendation
Immediately update the AR for WooCommerce plugin to the latest available version that fixes this vulnerability. If an update is not possible, consider temporarily disabling the plugin.
Original NVD description (English source)
The AR for WooCommerce 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. The three intended access controls all fail: valid nonces are freely minted by unauthenticated callers via the nopriv ar_get_fresh_nonce and ar_process_user_image AJAX handlers; the AES-256-CBC encryption key is derived from get_option('ar_licence_key'), which returns false on default free installations and yields a predictable key attackers can use to encrypt their own path payloads; and the Referer check is trivially bypassed because the Referer header is attacker-controlled.
