Name of the Vulnerable Software and Affected Versions UserPro plugin for WordPress versions up to, and including, 5.1.5

Description The issue is related to Stored Cross-Site Scripting via the 'userpro' shortcode due to insufficient input sanitization and output escaping on user-supplied attributes. This allows authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Recommendations For versions up to, and including, 5.1.5, update to a version later than 5.1.5 to resolve the issue. As a temporary workaround, consider restricting access to the 'userpro' shortcode for users with contributor-level and above permissions until a patch is available. Additionally, ensure proper input sanitization and output escaping for all user-supplied attributes to minimize the risk of exploitation.
