Name of the Vulnerable Software and Affected Versions aThemes Starter Sites plugin for WordPress versions up to, and including, 1.0.53

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, 1.0.53, update to a version higher than 1.0.53 to resolve the issue. As a temporary workaround, consider restricting file uploads, especially SVG files, to prevent potential exploitation until a patch is available. Additionally, limiting access to Author-level and above users can help minimize the risk of exploitation.
