EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.7 under NVD CVSS v3. EPSS exploit probability: 0.3%, top 81% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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 ` 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 ` element and executes arbitrary JavaScript in the admin's browser. Versions 1.5.10.1832 and 1.6.0-beta.2313 fix the issue.
