CVE-2026-25347Network attack vector

Admin script execution via unescaped cache keys

Published Mar 25, 2026 · Updated Mar 25, 2026

Stored XSS in Acato WP REST Cache 2026.1.0 and earlier allows remote attackers to execute scripts in an administrator's browser. The cache list table prints attacker-influenced cache_key values without HTML escaping, so a crafted REST request persists executable markup. Exploitation requires no account, but script execution occurs only when a privileged user opens the affected cache administration view.
