CVE-2025-11360Network attack vector

Browser script execution via unserialized ingress header

Published Oct 7, 2025 · Updated Oct 7, 2025

Cross-site scripting in Double Take 1.13.0 through 1.13.1 allows remote attackers to execute script in a visitor's browser. The API handler in api/src/app.js inserts the X-Ingress-Path request header between single quotes in an inline script without safe serialization. No authentication is required, but a visitor must load the affected UI response; the injected script can alter content in that browser context.
