Vulnerability Overview

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.

Technical Analysis

REMEDIATION: Update to version 2.7.8, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
