Stored Cross-Site Scripting in Clubmember Plugin by WordPress

CVE-2025-12396

What is CVE-2025-12396?

The Clubmember plugin for WordPress is susceptible to Stored Cross-Site Scripting, allowing authenticated attackers with administrator privileges to insert arbitrary web scripts. This vulnerability stems from inadequate input sanitization and output escaping in the plugin's admin settings. Consequently, when a user visits an affected page, the injected scripts execute, leading to potential security threats and data exposure. The issue specifically impacts multi-site installations and those where unfiltered HTML is disabled.
