Name of the Vulnerable Software and Affected Versions Easy Custom Admin Bar plugin for WordPress version 1.0 and earlier

Description The issue is related to Reflected Cross-Site Scripting via the msg parameter due to insufficient input sanitization and output escaping. This allows 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.

Recommendations For versions up to and including 1.0, consider disabling the msg parameter until a patch is available to prevent exploitation. Restrict access to areas where the Easy Custom Admin Bar plugin is used to minimize the risk of arbitrary web script injection. Avoid using the msg parameter in affected areas until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
