Vulnerability Overview

The "Buy Me a Coffee – Button and Widget Plugin" plugin for WordPress is vulnerable to Cross-Site Scripting in versions up to, and including, 3.6 due to insufficient sanitization and escaping on the 'text value set via the bmc_post_reception action. This makes it possible for authenticated attackers, with subscriber-level permissions, and above to inject arbitrary web scripts into pages that execute whenever a victim accesses a page with the injected scripts.

Technical Analysis

REMEDIATION: Update to version 3.7, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
