Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in WP Codeus Advanced Sermons allows Stored XSS. This issue affects Advanced Sermons: from n/a through 3.6.
AnalysisAI
Stored cross-site scripting in Advanced Sermons WordPress plugin up to version 3.6 allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts into sermon pages. These scripts execute when other users view the affected pages, potentially leading to session hijacking or defacement. No public exploit or active exploitation has been identified.
Technical ContextAI
The vulnerability is a stored cross-site scripting (XSS) issue in the Advanced Sermons WordPress plugin, which manages sermon content. The root cause is improper neutralization of user-supplied input during web page generation (CWE-79). Attackers with low-privileged roles (e.g., contributor) can inject malicious scripts that are stored and later executed in the browsers of other users, including administrators. The CVSS vector indicates a network attack vector, low attack complexity, low privileges required, and user interaction required (victim must visit the page).
RemediationAI
Upgrade Advanced Sermons to version 3.7 or later, which contains the fix per the vendor advisory. No workarounds are documented; as a compensating control, restrict contributor-level access to trusted users only, or disable the plugin if not in use.
