Vulnerability Overview

The Leyka plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.29.2. This makes it possible for unauthenticated attackers to perform an unknown action granted they can trick a site administrator into performing an action such as clicking on a link. The impact of this vulnerability is unknown.

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-352: Cross-Site Request Forgery (CSRF)

Reaching this weakness in Leyka <= 3.29.2 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.

An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For Leyka the fix is 3.30: builds <= 3.29.2 are affected, anything from 3.30 onward is not.

Remediation

Update to version 3.30, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Leyka: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Leyka 3.30 closes this, and updating the plugin is the step that ends it.
