CVE-2026-47689: Fogproject cross-site scripting vulnerability

Fogproject · Fogproject

FOG is a free open-source cloning/imaging/rescue suite/inventory management system. Prior to versions 1.5.10.1832 and 1.6.0-beta.2313, the `buildRow()` method in `fogpage.class.php` substitutes data values into HTML table cell templates using `str_replace()` without any HTML escaping. An unauthenticated attacker who knows any registered host's MAC address can POST malicious inventory values (e.g. `sysproduct`, `sysserial`) to `/service/inventory.php`, which stores them in the database. When an administrator opens the Group Inventory tab, the payload renders as executable HTML/JavaScript in the admin's browser. Versions 1.5.10.1832 and 1.6.0-beta.2313 fix the issue.
