{"id":"CVE-2026-8790","published":"2026-08-05T06:16:40.810","lastModified":"2026-08-05T17:16:57.380","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.","cvssScore":6.1,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://plugins.trac.wordpress.org/browser/football-pool/tags/2.13.4/widgets/widget-football-pool-shoutbox.php#L127","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/football-pool/tags/2.13.4/widgets/widget-football-pool-shoutbox.php#L142","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/football-pool/tags/2.13.4/widgets/widget-football-pool-shoutbox.php#L84","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/football-pool/trunk/widgets/widget-football-pool-shoutbox.php#L127","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/football-pool/trunk/widgets/widget-football-pool-shoutbox.php#L142","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/football-pool/trunk/widgets/widget-football-pool-shoutbox.php#L84","tags":[]},{"url":"https://plugins.trac.wordpress.org/changeset/3538628/football-pool/trunk/widgets/widget-football-pool-shoutbox.php","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/c5d17538-30ff-423c-bd61-d85a3f5aba74?source=cve","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
