Description

The iThemes Security plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘license’ parameter in versions before 3.6.4 due to insufficient input sanitization and output escaping. This makes it possible for attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Wordfence blocked 20,450,017 attacks targeting this vulnerability in the past 24 hours.
