What it is
From the CVE record
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.
In plain language
Written by AI from the recordEasy Custom Admin Bar versions through 1.0 let a scam link run unwanted code in a visitor’s browser, so businesses using it should remove or disable it until a safe update is available.
