What the vulnerability does
The Easy Custom Admin Bar plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘msg’ parameter in all versions up to, and including, 1.0 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.
Explanation of Vulnerability in Simple Terms
Easy Custom Admin Bar versions 1.0 and earlier contain a cross-site scripting (XSS) vulnerability. An attacker can inject malicious scripts that execute in the browsers of site visitors or administrators. The vulnerability requires user interaction—typically clicking a malicious link—and can affect other users or the site itself depending on where the injection occurs.
What an attacker can do
Inject malicious scripts that run in visitors' browsers, potentially stealing credentials or performing actions on their behalf.
Potential impact on your site
Visitors or admins could have their sessions hijacked, credentials stolen, or be redirected to malicious sites.
Conditions required to exploit
No authentication required. Victim must click a malicious link or visit an attacker-controlled page.
