CVE-2025-8429Network attack vector

Stored XSS via privileged ACL Action injection

Published Oct 14, 2025 · Updated Oct 14, 2025

Stored XSS in Centreon Infra Monitoring allows remote authenticated users with elevated privileges to inject script through ACL Actions. Centreon identifies the ACL Action access configuration page as the injection locus but has not disclosed the input field, storage path, or missing output-encoding operation. Elevated privileges are required to store the payload; when the affected page renders it, script executes in the viewer's browser context and can expose session-accessible data.
