Publicly Published April 20, 2015
Last Updated December 14, 2022

Description

The UpdraftPlus WordPress plugin for WordPress is vulnerable to Cross-Site Scripting via the 'add_query_arg()' and 'remove_query_arg()' functions in versions up to, and including, 1.9.6.3 due to insufficient input sanitization and output escaping. This makes it possible for attackers to inject arbitrary web scripts that execute in a victim's browser.
