What is CVE-2015-3440?

A Cross-Site Scripting (XSS) vulnerability existed in WordPress versions prior to 4.2.1, allowing remote attackers to inject arbitrary web scripts or HTML into comments. This vulnerability arose due to improper storage of long comments, which are limited by the MySQL TEXT data type. When users interact with infected comments, they may unknowingly execute malicious scripts, potentially compromising their accounts and exposing sensitive information.

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.
