CVE-2022-23543Public exploitNetwork attack vector

Viewer-context script execution via iframe event attributes

Published Dec 19, 2022 · Updated Apr 15, 2025

Stored cross-site scripting in SilverwareGames.io before 1.1.34 allows remote authenticated users to run script through a YouTube post. The post.php handler rejects non-YouTube links and strips tags but preserves attacker-supplied event attributes when generating an iframe. An authenticated posting account and viewer interaction are required, after which the script runs in the site's origin and can read or alter data available to that viewer.
