Stored XSS via unencoded directory names

Published Oct 1, 2026 · Updated Oct 1, 2026

Stored XSS in Pandora FMS 777 and later affected releases allows remote authenticated users to execute script through File Manager directory names. The Create Directory function accepts an unvalidated name and renders it in the File Manager interface without output encoding. Creating the directory requires high-level console privileges; the script executes when another user views the affected page, without a click.
