At a glance

CVE-2026-119480 is a medium-severity Improper Limitation of a Pathname to a Restricted Directory vulnerability in the JetFormBuilder WordPress plugin, affecting versions <= 3.6.7.1. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 3.6.8; sites on affected versions should update now. Disclosed October 2026, reported by nizar yart.

Vulnerability Overview

The JetFormBuilder — Dynamic Blocks Form Builder plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 3.6.7.1. This is due to missing ownership validation on attachment IDs supplied via the media-field upload preset JSON, allowing any authenticated user to reference attachments they did not upload and trigger their deletion through the media cleanup routine. This makes it possible for authenticated attackers, with subscriber-level access and above, to delete arbitrary media attachments by supplying a manipulated attachment ID in the media-field upload preset, which caused the cleanup routine to treat the referenced file as a prior upload belonging to the current submission.

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 interaction from a victim user.

CWE-22: Improper Limitation of a Pathname to a Restricted Directory

Reaching this weakness in JetFormBuilder <= 3.6.7.1 takes an account at Subscriber level or above. 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 JetFormBuilder the fix is 3.6.8: builds <= 3.6.7.1 are affected, anything from 3.6.8 onward is not.

Remediation

Update to version 3.6.8, or a newer patched version

How does WordSec protect against this?

An attacker needs Subscriber access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: JetFormBuilder 3.6.8 closes this, and updating the plugin is the step that ends it.
