The RSS Aggregator by Feedzy plugin for WordPress contains a Blind SSRF vulnerability (CWE-918) in the feedzy_lazy_load function affecting all versions up to 5.1.1. An unauthenticated attacker can exploit this flaw to induce the server to send HTTP requests to arbitrary locations, potentially allowing interaction with internal network services. The CVSS 3.1 base score is 5.8 (medium severity), reflecting network attack vector, low attack complexity, no privileges required, no user interaction, and partial confidentiality impact. No patch or vendor advisory information is currently available.

An attacker can leverage this SSRF vulnerability to make the vulnerable server send requests to arbitrary URLs, including internal services that may not be otherwise accessible externally. This can lead to unauthorized querying or modification of internal resources. The confidentiality impact is limited, with no direct integrity or availability impact reported. No known exploits in the wild have been documented.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider restricting outbound HTTP requests from the server hosting the plugin or applying network-level controls to limit access to internal services. Monitor official themeisle communications for updates regarding patches or mitigations.
