Overview

CVE-2026-8790 is a medium-severity vulnerability. It was published on August 5, 2026 and has a CVSS 3.1 base score of 6.1 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 6.1, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
