Official Description
FOG is a free open-source cloning/imaging/rescue suite/inventory management system. Prior to 1.5.10.1812, the listing tables on multiple management pages (Host, Storage, Group, Image, Printer, Snapin) are vulnerable to Stored Cross-Site Scripting (XSS), due to insufficient server-side parameter sanitization in record creations/updates and a lack of HTML escaping in listing tables. Version 1.5.10.1812 patches the issue.
Technical Analysis
CVE-2026-33739 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

A successful exploit results in complete confidentiality breach (data exposure), with a CVSS base score of 5.7.
From a weakness classification perspective (CWE-79): Cross-site scripting (XSS) vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users.
