This vulnerability affects the microkid Custom Author URL plugin, allowing an attacker to exploit a CSRF flaw to inject stored XSS payloads. The affected versions include all up to and including 2.0.1. The CVSS 3.1 base score is 7.1, indicating a high severity with network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and impacts on confidentiality, integrity, and availability. No known exploits in the wild or vendor patches are currently documented.

Successful exploitation could allow an attacker to execute stored XSS attacks via CSRF, potentially leading to unauthorized actions performed in the context of an authenticated user. This can result in partial compromise of confidentiality, integrity, and availability of the affected system or user data.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider disabling or limiting use of the affected plugin and apply any recommended security controls to mitigate CSRF and XSS risks.
