CVE-2021-46676

Script execution via transactional-map name injection

Published Aug 5, 2022 · Updated Jun 2, 2026

Cross-site scripting in Pandora FMS 756 and earlier allows attackers to execute JavaScript through a crafted transactional-map name. The console fails to neutralize the name value before placing it in a generated page, so the browser interprets injected script as code. Exploitation requires creation or editing of a transactional map and a user to render the affected name; successful execution occurs in that viewer's browser context.
