What is CVE-2026-14231?

The LifterLMS WordPress plugin prior to version 10.0.10 has a vulnerability that fails to adequately verify user capabilities in one of its AJAX handlers. This oversight allows any authenticated user, even those with minimal subscriber-level permissions, to access sensitive titles of internal post types, such as coupon codes, by merely providing the associated post type. This flaw could lead to unauthorized information disclosure and should be addressed promptly.

Affected Version(s)

LifterLMS 0 < 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.
