CVE-2024-9830 – Bard <= 2.216 - Reflected Cross-Site Scripting via add_query_arg Parameter

https://notcve.org/view.php?id=CVE-2024-9830

The Bard theme for WordPress is vulnerable to Reflected Cross-Site Scripting due to the use of add_query_arg without appropriate escaping on the URL in all versions up to, and including, 2.216. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. • https://themes.trac.wordpress.org/browser/bard/2.216/functions.php#L109 https://themes.trac.wordpress.org/browser/bard/2.216/functions.php#L98 https://themes.trac.wordpress.org/changeset/248854 https://wordpress.org/themes/bard https://www.wordfence.com/threat-intel/vulnerabilities/id/9aff1e5b-2f16-43d0-b75a-c07e59a9c15f?source=cve • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
