At a glance
CVE-2025-14344 is a critical-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the Multi Uploader for Gravity Forms WordPress plugin, affecting versions <= 1.1.7. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 1.1.8; sites on affected versions should update now. Disclosed December 2025, reported by Muhammad Yudha - DJ.
Vulnerability Overview
The Multi Uploader for Gravity Forms plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the 'plupload_ajax_delete_file' function in all versions up to, and including, 1.1.7. This makes it possible for unauthenticated attackers to delete arbitrary files on the server.
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 confidentiality, integrity, availability — full site compromise territory.
CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Multi Uploader for Gravity Forms <= 1.1.7 carries this weakness at plupload_ajax_delete_file, 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 Multi Uploader for Gravity Forms the fix is 1.1.8: builds <= 1.1.7 are affected, anything from 1.1.8 onward is not.
Remediation
Update to version 1.1.8, 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: Multi Uploader for Gravity Forms 1.1.8 closes this, and updating the plugin is the step that ends it.
