WordPress Push Notification for Post and BuddyPress Reflected Cross-Site Scripting Vulnerability

A reflected cross-site scripting vulnerability has been identified in the WordPress Push Notification for Post and BuddyPress plugin, affecting all versions through 2.06.

Reproduction

To reproduce this vulnerability, send a request to the WordPress site with the 'pushnotificationid' parameter. The injected script will be executed if the user clicks on the link containing the malicious payload.

Remediation

Users are advised to update the WordPress Push Notification for Post and BuddyPress plugin to version 2.08 or later.
