At a glance

CVE-2025-8151 is a medium-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the HT Mega Addons for Elementor WordPress plugin, affecting versions <= 2.9.1. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Author level or above. The issue is fixed in version 2.9.2; sites on affected versions should update now. Disclosed July 2025, reported by wesley (wcraft).

Vulnerability Overview

The HT Mega – Absolute Addons For Elementor plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 2.9.1 via the 'save_block_css' function. This makes it possible for authenticated attackers, with Author-level access and above, to create CSS files in any directory, and delete CSS files in any directory in a Windows environment.

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 ('Path Traversal')

HT Mega Addons for Elementor <= 2.9.1 carries this weakness at save_block_css, and reaching it takes an account at Author 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 HT Mega Addons for Elementor the fix is 2.9.2: builds <= 2.9.1 are affected, anything from 2.9.2 onward is not.

Remediation

Update to version 2.9.2, or a newer patched version

How does WordSec protect against this?

An attacker needs Author 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: HT Mega Addons for Elementor 2.9.2 closes this, and updating the plugin is the step that ends it.
