The vulnerability CVE-2025-22810 affects Phi Phan's Content Blocks Builder plugin (versions <= 2.7.6) and involves improper neutralization of input during web page generation, resulting in stored cross-site scripting (XSS). This allows attackers with at least low 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, privileges required, user interaction required, and scope change.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to information disclosure, session hijacking, or other impacts on confidentiality, integrity, and availability. The impact is rated medium based on the CVSS score of 6.5. There are no reports of active exploitation in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official patch or fix links are provided, users should monitor Phi Phan's official channels for updates. In the meantime, limiting privileges of users who can input content and applying web application firewall (WAF) rules to detect and block XSS payloads may reduce risk.
