What the vulnerability does
The Sermon Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `sermon-views` shortcode in all versions up to, and including, 2.30.0. This is due to insufficient input sanitization and output escaping on user-supplied attributes. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Explanation of Vulnerability in Simple Terms
Sermon Manager for WordPress contains a cross-site scripting (XSS) vulnerability in versions up to 2.30.0. An authenticated user with low privileges can inject malicious scripts that execute in other users' browsers, potentially affecting site visitors and administrators. The vulnerability has scope impact, meaning it can affect components beyond the plugin itself.
What an attacker can do
Inject malicious scripts that run in other users' browsers to steal data or perform actions on their behalf.
Potential impact on your site
Malicious users can compromise admin accounts, steal visitor data, or deface your site without requiring admin access.
Conditions required to exploit
