XSS in Fogproject
CVE-2026-47687
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 `selectForm()` helper in `fogpage.class.php` renders `<option>` labels using raw, unescaped user input. An unauthenticated attacker who knows any registered host's MAC address can POST a malicious `sysproduct` value to `/service/inventory.php`, which is stored in the database. When an administrator opens Reports > Inventory, the payload breaks out of the `<option>` element and executes arbitrary JavaScript in the admin's browser. Versions 1.5.10.1832 and 1.6.0-beta.2313 fix the issue.
