At a glance
CVE-2025-47535 is a medium-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the Opal Woo Custom Product Variation WordPress plugin, affecting versions <= 1.2.0. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.2.1; sites on affected versions should update now. Disclosed May 2025, reported by timomangcut.
Vulnerability Overview
The Opal Woo Custom Product Variation plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the owcpv_delete_fineuploader() function in all versions up to, and including, 1.2.0. 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.
CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Opal Woo Custom Product Variation <= 1.2.0 carries this weakness at owcpv_delete_fineuploader(), and reaching it 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 Opal Woo Custom Product Variation the fix is 1.2.1: builds <= 1.2.0 are affected, anything from 1.2.1 onward is not.
Remediation
Update to version 1.2.1, 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: Opal Woo Custom Product Variation 1.2.1 closes this, and updating the plugin is the step that ends it.
