CVE-2025-11467 is a Blind Server-Side Request Forgery (SSRF) vulnerability classified under CWE-918, affecting the WordPress plugin RSS Aggregator by Feedzy – Feed to Post, Autoblogging, News & YouTube Video Feeds Aggregator, specifically in the feedzy_lazy_load function. This vulnerability exists in all versions up to and including 5.1.1. SSRF vulnerabilities allow attackers to abuse the server to send crafted requests to arbitrary locations, including internal network services that are not directly accessible from the internet. In this case, the vulnerability is 'blind', meaning the attacker does not directly receive the response content but can infer information or cause side effects by interacting with internal services. The vulnerability is exploitable without authentication or user interaction, increasing its risk profile. The CVSS v3.1 base score is 5.8, reflecting medium severity, with attack vector network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and a scope change (S:C) indicating impact beyond the vulnerable component. The impact primarily affects confidentiality by potentially allowing attackers to query internal services and gather sensitive information. Integrity and availability impacts are not indicated. No known exploits have been reported in the wild, and no official patches or mitigations have been linked yet. The vulnerability affects a widely used WordPress plugin, increasing the potential attack surface globally.

The primary impact of CVE-2025-11467 is unauthorized internal network reconnaissance and potential information disclosure. Attackers can leverage the SSRF vulnerability to send crafted requests from the vulnerable web server to internal services, which may include databases, internal APIs, cloud metadata endpoints, or other sensitive infrastructure components. This can lead to leakage of sensitive data, such as credentials, configuration details, or private information not intended for external access. While the vulnerability does not directly allow code execution or denial of service, the ability to interact with internal services can be a critical stepping stone for further attacks, including lateral movement or privilege escalation. Organizations using the affected plugin on public-facing WordPress sites are at risk, especially if their internal network contains sensitive or critical systems accessible from the web server. The lack of authentication requirement and user interaction makes exploitation easier for attackers scanning for vulnerable sites. The medium severity score reflects a moderate but significant risk that requires timely attention to prevent exploitation.

1. Immediate mitigation should include disabling or removing the RSS Aggregator by Feedzy plugin until a security patch is released. 2. If removal is not feasible, restrict the web server's outbound HTTP requests using firewall rules or network segmentation to prevent unauthorized internal network access. 3. Monitor web server logs for unusual outbound requests or patterns indicative of SSRF exploitation attempts. 4. Implement web application firewall (WAF) rules to detect and block suspicious requests targeting the feedzy_lazy_load function or unusual URL parameters. 5. Limit the exposure of internal services by enforcing strict access controls and network segmentation to minimize the impact of SSRF. 6. Stay updated with vendor advisories and apply security patches promptly once available. 7. Conduct internal audits of all WordPress plugins to identify and remediate other potential vulnerabilities. 8. Educate site administrators about the risks of installing unvetted plugins and the importance of timely updates.
