Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190) and 1 other technique. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly addresses the insufficient file path validation in the plupload_ajax_delete_file function, preventing path traversal that enables arbitrary file deletion.

SI-2 Flaw Remediation good match

prevent

Remediates the specific flaw in Multi Uploader for Gravity Forms plugin versions up to 1.1.7 by identifying, testing, and deploying security patches.

AC-3 Access Enforcement good match

prevent

Enforces approved authorizations to block unauthenticated access to the vulnerable AJAX delete endpoint, stopping remote exploitation.

NVD Description

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.

Deeper analysisAI

CVE-2025-14344 is a path traversal vulnerability (CWE-22) in the Multi Uploader for Gravity Forms plugin for WordPress, affecting all versions up to and including 1.1.7. The issue stems from insufficient file path validation in the 'plupload_ajax_delete_file' function, enabling arbitrary file deletion on the server. Published on 2025-12-12, it carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), reflecting its critical severity due to high impacts across confidentiality, integrity, and availability.

Unauthenticated attackers can exploit this vulnerability remotely over the network with low attack complexity and no user interaction or privileges required. By crafting malicious requests to the affected function, they can delete arbitrary files on the web server, potentially disrupting services, destroying data, or enabling further compromise through targeted deletions such as configuration files or backups.

Mitigation details are available in referenced advisories, including the Wordfence threat intelligence page (https://www.wordfence.com/threat-intel/vulnerabilities/id/346af237-0411-4cc4-9544-eab697385a2f?source=cve), the plugin's vulnerable code at lines 41-43 in GFMUHandlePluploader.class.php (https://plugins.trac.wordpress.org/browser/gf-multi-uploader/tags/1.1.7/inc/GFMUHandlePluploader.class.php?marks=41-43#L41), and WordPress plugin trac changeset 3421317 (https://plugins.trac.wordpress.org/changeset/3421317/), which addresses the flaw. Security practitioners should update to a version beyond 1.1.7 and review access to the plugin's AJAX endpoints.
