CVE-2025-39558Network attack vector

Unauthenticated reflected script execution via ticket submission

Published Apr 17, 2025 · Updated Apr 28, 2026

Reflected XSS in ticket submission in CRM Perks support-x 1.1.7 and earlier allows remote attackers to execute browser script. Public records identify ticket submission as the affected locus but do not disclose which request field is reflected or where output encoding fails. Exploitation requires a visitor to open a crafted request; the injected script runs in the site's origin and grants access to browser-accessible data and actions.
