What is CVE-2026-92438?

The Ninja Forms plugin for WordPress, specifically version 3.15.3, is susceptible to a vulnerability due to its failure to properly escape submitted form field values. This oversight allows unauthenticated users to submit data through publicly accessible forms. When these values are displayed on the submission edit screen in the admin area, they could be executed in the browser of any privileged user accessing this screen, potentially leading to unauthorized actions or data exposure.

Affected Version(s)

Ninja Forms 3.15.3 < 3.15.4

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.
