CWE-79

The SEO Redirection Plugin – 301 Redirect Manager WordPress plugin before 6.4 did not sanitise the Redirect From and Redirect To fields when creating a new redirect in the dashboard, allowing high privilege users (even with the unfiltered_html disabled) to set XSS payloads

The Advanced Custom Fields Pro WordPress plugin before 5.9.1 did not properly escape the generated update URL when outputting it in an attribute, leading to a reflected Cross-Site Scripting issue in the update settings page.

An AJAX action registered by the WPBakery Page Builder (Visual Composer) Clipboard WordPress plugin before 4.5.6 did not have capability checks nor sanitization, allowing low privilege users (subscriber+) to call it and set XSS payloads, which will be triggered in all backend pages.

The Stop Spammers WordPress plugin before 2021.9 did not escape user input when blocking requests (such as matching a spam word), outputting it in an attribute after sanitising it to remove HTML tags, which is not sufficient and lead to a reflected Cross-Site Scripting issue.

The Workscout Core WordPress plugin before 1.3.4, used by the WorkScout Theme did not sanitise the chat messages sent via the workscout_send_message_chat AJAX action, leading to Stored Cross-Site Scripting and Cross-Frame Scripting issues
