Name of the Vulnerable Software and Affected Versions The Bard theme for WordPress versions up to, and including, 2.216

Description The issue arises from the use of add query arg without proper escaping on the URL, leading to Reflected Cross-Site Scripting. This allows unauthenticated attackers to inject arbitrary web scripts into pages, which execute when a user performs a specific action, such as clicking on a link.

Recommendations For versions up to, and including, 2.216, update to a version that properly escapes URLs using add query arg to prevent Reflected Cross-Site Scripting attacks. As a temporary workaround, consider implementing additional validation and sanitization for user-inputted URLs to minimize the risk of exploitation.
