At a glance

CVE-2026-19952 is a high-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the Frontend Admin by DynamiApps WordPress plugin, affecting versions <= 3.29.12. It carries a CVSS score of 7.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires no authentication. The issue is fixed in version 3.29.13; sites on affected versions should update now. Disclosed August 2026, reported by nudien.

Vulnerability Overview

The Frontend Admin by DynamiApps plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the move_folders function in all versions up to, and including, 3.29.12. 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). This is exploitable without authentication when a form is configured with public visibility (who_can_see='all'), as the required nonce is publicly obtainable from the rendered form.

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.

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

Frontend Admin by DynamiApps <= 3.29.12 carries this weakness at all, 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 Frontend Admin by DynamiApps the fix is 3.29.13: builds <= 3.29.12 are affected, anything from 3.29.13 onward is not.

Remediation

Update to version 3.29.13, 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: Frontend Admin by DynamiApps 3.29.13 closes this, and updating the plugin is the step that ends it.
