What is CVE-2026-14207?

The LifterLMS plugin for WordPress prior to version 10.0.10 is susceptible to a cross-site scripting vulnerability. This flaw arises from the plugin's failure to sanitize event-handler attributes within a course pricing field. As a result, users with editing privileges can inject malicious JavaScript code that gets executed in the session of an administrator who accesses the course, leading to potential security risks and unauthorized actions.

Affected Version(s)

LifterLMS 9.2.3 < 10.0.10

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
