At a glance

CVE-2026-110253 is a medium-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the weForms WordPress plugin, affecting versions <= 1.6.28. It carries a CVSS score of 5.4 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.6.29; sites on affected versions should update now. Disclosed October 2026, reported by Kuba.

Vulnerability Overview

The weForms – Easy Drag & Drop Contact Form Builder For WordPress plugin for WordPress is vulnerable to limited media file deletion due to insufficient file path validation in the weforms_delete_entry_attachments function in all versions up to, and including, 1.6.28 This makes it possible for unauthenticated attackers to delete arbitrary media files on the server. This requires an administrator to permanently delete the poisoned form entry, a routine moderation action for spam-looking submissions that an attacker can prompt through social engineering.

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.

CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Reaching this weakness in weForms <= 1.6.28 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 weForms the fix is 1.6.29: builds <= 1.6.28 are affected, anything from 1.6.29 onward is not.

Remediation

Update to version 1.6.29, 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: weForms 1.6.29 closes this, and updating the plugin is the step that ends it.
