Jabbernotification vulnerability

What happened

The Jabbernotification plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the admin.php PATH_INFO in all versions up to, and including, 0.99-RC2 due to insufficient input sanitization and output escaping. 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.

Affected versions

Jabbernotification: 0 through 0.99-RC2 (semver) Fixed: See vendor advisory.
