Name of the Vulnerable Software and Affected Versions Your Simple SVG Support plugin for WordPress versions up to, and including, 1.0.1

Description The issue is related to Stored Cross-Site Scripting via SVG File uploads 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 the SVG file.

Recommendations For versions up to, and including, 1.0.1, update to a version that addresses the insufficient input sanitization and output escaping issue to prevent Stored Cross-Site Scripting attacks. As a temporary workaround, consider restricting access to SVG file uploads for users with Author-level access and above until a patch is available.
