At a glance

CVE-2025-26940 is a medium-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the Pie Register Premium WordPress plugin, affecting versions <= 3.8.3.2. 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 3.8.3.3; sites on affected versions should update now. Disclosed February 2025, reported by Ananda Dhakal.

Vulnerability Overview

The Pie Register Premium plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 3.8.3.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete limited files from the server.

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')

Reaching this weakness in Pie Register Premium <= 3.8.3.2 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 Pie Register Premium the fix is 3.8.3.3: builds <= 3.8.3.2 are affected, anything from 3.8.3.3 onward is not.

Remediation

Update to version 3.8.3.3, 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: Pie Register Premium 3.8.3.3 closes this, and updating the plugin is the step that ends it.
