CVE-2026-11370
Description
The WP Meta SEO plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 4.5.18 via the 'new_link' parameter. This makes it possible for authenticated attackers, with contributor-level access and above, to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services. The HTTP response status from outbound requests is reflected back in the AJAX JSON response as status_code, providing an enumeration oracle usable for probing internal hosts and cloud metadata services.
Summary dbcve.org
The WP Meta SEO plugin for WordPress versions up to 4.5.18 contains an unauthenticated SSRF vulnerability via the 'new_link' parameter. Authenticated attackers with contributor-level access can make arbitrary HTTP requests from the server and receive reflected HTTP status codes in AJAX responses, enabling probing of internal hosts and cloud metadata services.
Mitigation
Update WP Meta SEO plugin to version beyond 4.5.18 when available; until then, restrict contributor-level user permissions and implement server-side URL allowlist validation for the 'new_link' parameter.
