CVE-2025-49947Network attack vector

Unauthenticated browser script execution

Published Oct 22, 2025 · Updated Oct 22, 2025

Reflected XSS in Extendons Custom Registration Fields for WooCommerce 3.2.3 and earlier allows remote attackers to run scripts in a user's browser. The public CNA-linked advisory does not identify the vulnerable request parameter, handler, or output operation that reflects untrusted input without adequate neutralization. Exploitation requires no account but does require a user to interact with attacker-controlled input, bounding the impact to script execution in that user's browser context.
