The Template Kit – Import plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the template upload functionality in all versions up to, and including, 1.0.14 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Envato Elements & Download and Template Kit – Import plugins for WordPress are vulnerable to arbitrary file uploads due to insufficient validation of file type upon extracting uploaded Zip files in the installFreeTemplateKit and uploadTemplateKitZipFile functions. This makes it possible for attackers with contributor-lever permissions and above to upload arbitrary files and potentially gain remote code execution in versions up to and including 1.0.13 of Template Kit – Import and versions up to and including 2.0.10 of Envato Elements & Download.
