Vulnerability from github – Published: 2026-08-05 06:30 – Updated: 2026-08-05 06:30

Details

The Football Pool plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the shouttext POST parameter of the Shoutbox widget in all versions up to, and including, 2.13.4 due to insufficient input sanitization and output escaping. When a shoutbox form submission fails the nonce check (or shouttext is empty, or the user is unable to save), the raw POST value is echoed back into a <textarea> element using printf('%s', ...) with no HTML escaping. This makes it possible for unauthenticated attackers to execute arbitrary web scripts in the browser of an authenticated victim (Subscriber-level or higher) who is tricked into submitting a crafted POST request to a page that contains the Shoutbox widget.

Severity
6.1 (Medium)
