Name of the Vulnerable Software and Affected Versions MembershipWorks – Membership, Events & Directory plugin for WordPress versions prior to 6.14

Description The plugin is susceptible to Stored Cross-Site Scripting through admin settings due to inadequate input sanitization and output escaping. This allows authenticated attackers with administrator-level permissions or higher to inject arbitrary web scripts into pages. These scripts will execute when a user accesses the injected page.
