Summary

The Autoptimize WordPress plugin before 2.7.8 does not check for malicious files such as .html in the archive uploaded via the 'Import Settings' feature. As a result, it is possible for a high privilege user to upload a malicious file containing JavaScript code inside an archive which will execute when a victim visits index.html inside the plugin directory.
