Name of the Vulnerable Software and Affected Versions The ARMember Lite - Membership Plugin for WordPress versions up to, and including, 4.0.14

Description The issue is related to Stored Cross-Site Scripting via admin settings due to insufficient input sanitization and output escaping. This allows authenticated attackers with administrator-level permissions and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The issue only affects multi-site installations and installations where unfiltered html has been disabled.

Recommendations For versions up to, and including, 4.0.14, update to a version later than 4.0.14 to resolve the issue. As a temporary workaround, consider restricting access to admin settings to minimize the risk of exploitation. Additionally, ensure that unfiltered html is enabled, if possible, to reduce the vulnerability's impact.
