CVE-2026-56043Network attack vector

Unauthenticated stored XSS via unescaped review input

Published Jun 26, 2026 · Updated Jun 26, 2026

Stored XSS in CusRev Customer Reviews for WooCommerce 5.110.1 and earlier allows remote attackers to inject scripts through review submissions. Published records do not identify the affected parameter or function; they state that the plugin stores untrusted review input without sufficient sanitization and later renders it without context-appropriate escaping. No account is required, but a user must open an affected page; the script then runs in that viewer's browser under the site's origin.
