CVE-2025-11467 is a Server-Side Request Forgery (SSRF) vulnerability classified under CWE-918 found in the WordPress plugin 'RSS Aggregator by Feedzy – Feed to Post, Autoblogging, News & YouTube Video Feeds Aggregator' developed by themeisle. This vulnerability exists in all versions up to and including 5.1.1 and is triggered via the feedzy_lazy_load function. SSRF vulnerabilities allow attackers to abuse a vulnerable server to send crafted HTTP requests to arbitrary internal or external resources, effectively making the server a proxy. In this case, the vulnerability is 'blind', meaning the attacker may not directly see the response but can infer success through side effects or timing. The flaw requires no authentication or user interaction, increasing its risk profile. Exploitation can lead to unauthorized querying or modification of internal services that are otherwise inaccessible externally, potentially exposing sensitive data or enabling further attacks such as internal network reconnaissance or lateral movement. The CVSS v3.1 base score is 5.8 (medium severity) with vector AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N, indicating network attack vector, low complexity, no privileges or user interaction required, and a scope change with limited confidentiality impact. No known public exploits have been reported yet, but the vulnerability is publicly disclosed and should be addressed promptly.

For European organizations, this vulnerability poses a risk primarily to the confidentiality of internal network resources. Attackers can leverage the SSRF flaw to access internal services that are not exposed externally, potentially extracting sensitive information or interacting with internal APIs. This can facilitate further attacks such as privilege escalation, data exfiltration, or disruption of internal operations. Since the plugin is widely used in WordPress sites for content aggregation, organizations relying on it for news feeds or autoblogging may have their web servers exposed to SSRF exploitation. The impact is heightened in environments where internal services lack proper segmentation or access controls. Additionally, the vulnerability's unauthenticated nature means attackers can exploit it remotely without credentials, increasing the attack surface. Although no known exploits are in the wild, the public disclosure increases the risk of future exploitation attempts. European entities with critical internal services or sensitive data accessible via internal networks are particularly at risk.

1. Immediate mitigation involves disabling or removing the vulnerable plugin until an official patch is released by themeisle. 2. Monitor themeisle’s official channels for updates and apply patches promptly once available. 3. Implement strict egress filtering on web servers to restrict outbound HTTP requests only to trusted destinations, preventing SSRF exploitation from reaching internal services. 4. Deploy Web Application Firewalls (WAFs) with SSRF detection rules to identify and block suspicious request patterns targeting the feedzy_lazy_load function or similar endpoints. 5. Conduct internal network segmentation to isolate critical services from web-facing servers, reducing the impact of SSRF attacks. 6. Review and harden internal service authentication and authorization mechanisms to prevent unauthorized access even if SSRF is exploited. 7. Enable detailed logging and monitoring of outbound requests from web servers to detect anomalous activity indicative of SSRF attempts. 8. Educate site administrators about the risks of using outdated plugins and the importance of timely updates.
