CVE-2022-47606Network attack vector

Stored script execution via unescaped allowed domains

Published May 10, 2023 · Updated Apr 28, 2026

Stored cross-site scripting in Tim Stephenson WP-CORS 0.2.1 and earlier allows remote authenticated users to execute scripts in visitors' browsers. The Allowed domains setting stores administrator-supplied content without sufficient input sanitization and outputs it on a settings page without sufficient escaping. Administrator access is required, and exploitation is limited to multisite installations or installations with unfiltered_html disabled; a user must open the injected page.
