What is CVE-2020-26135?

Live Helper Chat versions before 3.44 are susceptible to a reflected cross-site scripting (XSS) vulnerability. This issue arises when user input is not properly sanitized in the setsettingajax endpoint, allowing attackers to inject malicious scripts that may be executed in the context of the user's browser. If exploited, this vulnerability could lead to unauthorized actions and compromise sensitive user 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.
