What is CVE-2023-5662?

The Sponsors plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) through the 'sponsors' shortcode. This vulnerability arises from inadequate input sanitization and output escaping of user-supplied attributes. As a result, authenticated attackers with contributor-level permissions or higher can inject malicious scripts into the web pages. These scripts execute whenever a user accesses the affected pages, potentially compromising sensitive user data and site integrity. Users are advised to update to the latest version of the plugin to mitigate this security risk.

Affected Version(s)

Sponsors * <= 3.5.0
