CVE-2022-42100Public exploitNetwork attack vector

Stored script execution via reply location input

Published Nov 29, 2022 · Updated Apr 25, 2025

Stored cross-site scripting in KLiK SocialMediaWebsite 1.0.1 allows remote authenticated users to execute script via a reply location. The reply form stores attacker-controlled location input and later renders it without effective neutralization, causing the payload to execute in another user's browser. A low-privileged account must submit the crafted field and another user must view the stored reply; execution can read or alter data available to that browser session.
