CVE-2025-22825Network attack vector

Stored XSS via unescaped template content

Published Jan 21, 2025 · Updated Apr 28, 2026

Stored XSS in WP Desk Flexible PDF Coupons before 1.10.3 allows remote authenticated users to inject scripts through the template editor. The editor insufficiently sanitizes template content and fails to escape it when generating a page, leaving attacker-supplied script stored for later rendering. Contributor-level access is required, and the script executes only when another user opens the affected page, exposing that user's browser session to script actions.
