At a glance
CVE-2026-32522 is a critical-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the WooCommerce Support Ticket System WordPress plugin, affecting versions < 18.5. It carries a CVSS score of 9.1 (reachable over the network; low attack complexity; high integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 18.5; sites on affected versions should update now. Disclosed March 2026, reported by Phat RiO.
Vulnerability Overview
The WooCommerce Support Ticket System plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in all versions up to 18.5 (exclusive). This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php).
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on integrity, availability.
CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Reaching this weakness in WooCommerce Support Ticket System < 18.5 takes no account at all. Path traversal happens when user-controlled text is used to build a filesystem path without being constrained to an intended directory, so sequences like ../ walk the resolved path somewhere else.
Depending on the operation, it means reading files outside the intended folder — wp-config.php being the usual target — or writing to and deleting paths the web server can touch. For WooCommerce Support Ticket System the fix is 18.5: builds < 18.5 are affected, anything from 18.5 onward is not.
Remediation
Update to version 18.5, or a newer patched version
How does WordSec protect against this?
Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WooCommerce Support Ticket System 18.5 closes this, and updating the plugin is the step that ends it.
