CVE-2022-40408Public exploitNetwork attack vector

Stored script execution via unsanitized comment image

Published Sep 29, 2022 · Updated May 20, 2025

Stored cross-site scripting in FeehiCMS 2.1.1 allows remote authenticated users to execute script in visitors' browsers via a comment. The Single Page module saves a crafted image src value supplied through the Comment box and renders it without neutralizing an onerror handler. A registered user must submit the payload and another user must load an affected page, exposing that browser session to unauthorized reads or changes.
