The vulnerability CVE-2025-30928 affects the vicchi WP Biographia plugin for WordPress, specifically versions up to 4.0.0. It is a stored cross-site scripting (XSS) flaw caused by improper input neutralization during the generation of web pages. This allows an attacker with high privileges and requiring user interaction to inject malicious scripts that can impact confidentiality, integrity, and availability to a limited extent. The CVSS vector indicates network attack vector, low attack complexity, high privileges required, user interaction required, and a scope change with low impact on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability could allow an attacker with high privileges to inject malicious scripts that execute in the browsers of users who view the affected pages. This can lead to limited confidentiality, integrity, and availability impacts such as session hijacking, defacement, or other malicious actions within the context of the affected site. However, exploitation requires user interaction and high privileges, which reduces the overall risk.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict high privilege user access to trusted individuals only and consider disabling or removing the WP Biographia plugin if feasible. Monitor for vendor updates regarding patches or official mitigations.
