CVE-2026-45231Network attack vector

Stored script execution via unescaped asset fields

Published May 18, 2026 · Updated May 18, 2026

Stored XSS in DumbWare DumbAssets 1.0.11 and earlier allows remote attackers to run scripts via crafted asset fields. Asset API handlers persist name, description, modelNumber, serialNumber, and tags without sanitization, and the asset list assigns them to innerHTML without escaping. Execution requires another user to view the asset list; with CSP disabled, the script can connect to internal network services from that browser.
