Published Oct 16, 2026 · Updated Oct 16, 2026 · Assigned by Wordfence

Vendor: jfarthing84 Product: Theme My Login Category: Web / CMS

Description

The Theme My Login plugin for WordPress is vulnerable to privilege escalation via account takeover in versions up to, and including, 7.2.1. This is due to the plugin not properly validating a user's identity prior to updating their password. This makes it possible for unauthenticated attackers to change arbitrary user's passwords on multi-site setups in certain configurations.
