Name of the Vulnerable Software and Affected Versions PostX plugin for WordPress versions up to, and including, 4.1.1

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

Recommendations For versions up to, and including, 4.1.1, update to a version that addresses the insufficient input sanitization and output escaping in the file uploading feature to prevent Stored Cross-Site Scripting attacks. As a temporary workaround, consider restricting access to the file uploading feature to minimize the risk of exploitation.
