Name of the Vulnerable Software and Affected Versions Schema App Structured Data plugin for WordPress versions up to, and including, 2.2.4

Description The issue arises from the use of add query arg without proper escaping on the URL, allowing unauthenticated attackers to inject arbitrary web scripts in pages. This can be executed if attackers successfully trick a user into performing an action, such as clicking on a link. The estimated number of potentially affected devices worldwide is not specified. There is no information provided about real-world incidents where this issue was exploited.

Recommendations For versions up to, and including, 2.2.4, update to a version higher than 2.2.4 to resolve the issue. As a temporary workaround, consider restricting access to potentially vulnerable pages until a patch is available. Avoid using the add query arg function without proper escaping on the URL until the issue is resolved.
