Input validation vulnerability in WP-Matomo Integration (WP-Piwik) 1.0.10

The WP-Matomo Integration (WP-Piwik) plugin for WordPress is vulnerable to a security issue known as Stored Cross-Site Scripting. This issue affects versions of the plugin before 1.0.11. It occurs because the plugin does not properly filter user input or escape output. This means that malicious actors may be able to inject malicious scripts into pages. When a user visits the page, the malicious script will run. This could allow the malicious actor to take control of the page and access user data. To prevent this issue, make sure to update to version 1.0.11 of the plugin.
