What is CVE-2025-13732?

The s2Member plugin, designed for managing memberships and content restriction on WordPress, suffers from a Stored Cross-Site Scripting vulnerability due to inadequate input sanitization and output escaping capabilities. Specifically, the vulnerability arises in the plugin's 's2Eot' shortcode, permitting authenticated attackers with Contributor-level access or higher to inject malicious web scripts. These scripts execute when users visit pages containing the malicious injection, posing significant risks to site integrity and user data.
