Name of the Vulnerable Software and Affected Versions Embed PDF Viewer plugin for WordPress versions up to, and including, 2.4.4

Description The issue is related to Stored Cross-Site Scripting via the height and width parameters due to insufficient input sanitization and output escaping. 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 versions up to, and including, 2.4.4, update to a version that includes the necessary input sanitization and output escaping fixes to prevent Stored Cross-Site Scripting attacks. As a temporary workaround, consider restricting access to the height and width parameters in the Embed PDF Viewer plugin until a patch is available.
