What is CVE-2026-9570?

The Taskbuilder plugin for WordPress, versions prior to 5.0.8, is susceptible to a Reflected Cross-Site Scripting vulnerability due to improper sanitization of a URL parameter. This flaw allows an attacker to inject malicious JavaScript code into a frontend page that utilizes one of the plugin's shortcodes. When this page is accessed by a logged-in user, the injected script is executed in the context of their session, potentially compromising their security and privacy.

Affected Version(s)

Taskbuilder 0 < 5.0.8
