AI Analysis
Technical Summary
CVE-2026-11370 is a Server-Side Request Forgery vulnerability (CWE-918) in the WP Meta SEO plugin for WordPress. It affects all versions up to and including 4.5.18. The flaw is triggered through the 'new_link' parameter, enabling authenticated users with contributor or higher privileges to cause the server to make arbitrary HTTP requests. The HTTP response status code from these requests is returned in the AJAX JSON response as 'status_code', which can be used as an enumeration oracle to probe internal hosts and cloud metadata services. This vulnerability can lead to unauthorized information disclosure and internal network reconnaissance.
Potential Impact
An attacker with contributor-level access or above can exploit this SSRF vulnerability to send arbitrary HTTP requests from the server hosting the WordPress site. This can be used to access internal services that are not normally reachable externally, potentially disclosing sensitive information. The reflected HTTP status code in the AJAX response aids attackers in enumerating internal hosts and cloud metadata endpoints. The CVSS 3.1 base score is 6.4 (medium severity), indicating a moderate impact with low complexity and no user interaction required.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level access and above to trusted users only. Monitor for updates from the vendor (joomunited) regarding patches or official mitigations. Avoid exposing sensitive internal services that could be targeted via SSRF.
