Security Summary

CVE-2025-25139 is a Cross-Site Request Forgery (CSRF) vulnerability in the WP Custom Post RSS Feed plugin developed by Cynob IT Consultancy for WordPress. The flaw enables Stored XSS and affects all versions of the plugin from its initial release through 1.0.0.

Attackers require no privileges and can exploit this over the network with low attack complexity, though user interaction is needed. Successful exploitation changes the security scope and results in low impacts to confidentiality, integrity, and availability, yielding a CVSS v3.1 base score of 7.1. An unauthenticated adversary can trick an authenticated user, such as an administrator, into performing a state-changing action via a forged request, leading to the storage of malicious XSS payloads that execute for subsequent visitors.

Patchstack advisories detail this CSRF-to-Stored XSS vulnerability in WP Custom Post RSS Feed version 1.0.0, urging WordPress administrators to review the plugin's status and apply recommended mitigations.
