The vulnerable endpoint (wp_ajax_nopriv_redux_p) accepts a 'url' parameter from the query string, passes it directly to WordPress\u2019s wp_remote_request() function without validation, and returns the response to the caller. Because no authentication, nonce, or URL whitelisting is enforced, an unauthenticated user can read the content of arbitrary internal or external resources, including cloud metadata endpoints or protected internal services. This can lead to information disclosure, internal network discovery, or potential further exploitation of downstream services.", "risk_and_exploitability": "The CVSS score of 7.2 reflects a moderate to high risk due to the lack of authentication and input validation. Exploitation requires only an unauthenticated HTTP request to the exposed AJAX endpoint; no special conditions are needed.

Consequently, the likelihood of exploitation remains moderate to high in environments where the plugin is active and exposed to the internet."}}}}, "created": "2026-03-23T09:49:43.471212+00:00", "updated": "2026-03-25T14:41:21.893525+00:00", "vendors": ["benmoody", "benmoody$PRODUCT$content_syndication_toolkit", "wordpress", "wordpress$PRODUCT$wordpress"]}
