Name of the Vulnerable Software and Affected Versions Editor Custom Color Palette plugin for WordPress versions up to, and including, 3.3.7

Description The issue arises from insufficient input sanitization and output escaping, allowing authenticated attackers with Author-level access and above to inject arbitrary web scripts in pages via SVG File uploads. This enables the execution of scripts whenever a user accesses the uploaded SVG file.
