Name of the Vulnerable Software and Affected Versions Passster plugin for WordPress versions up to, and including, 4.2.6.4

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

Recommendations For Passster plugin for WordPress versions up to, and including, 4.2.6.4, update to a version that addresses the insufficient input sanitization and output escaping issue. As a temporary workaround, consider restricting access to the content protector shortcode to minimize the risk of exploitation.
