{"id":"CVE-2026-8790","state":"PUBLISHED","title":"Football Pool <= 2.13.4 - Authenticated (Subscriber+) Reflected Cross-Site Scripting","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.","publishedAt":"2026-08-05T04:25:26.540Z","updatedAt":"2026-08-05T16:19:40.108Z","severity":{"score":6.1,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["antoineh Football Pool"],"affected":[{"vendor":"antoineh","product":"Football Pool","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.13.4","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/c5d17538-30ff-423c-bd61-d85a3f5aba74?source=cve","https://plugins.trac.wordpress.org/browser/football-pool/trunk/widgets/widget-football-pool-shoutbox.php#L142","https://plugins.trac.wordpress.org/browser/football-pool/tags/2.13.4/widgets/widget-football-pool-shoutbox.php#L142","https://plugins.trac.wordpress.org/browser/football-pool/trunk/widgets/widget-football-pool-shoutbox.php#L84","https://plugins.trac.wordpress.org/browser/football-pool/tags/2.13.4/widgets/widget-football-pool-shoutbox.php#L84","https://plugins.trac.wordpress.org/browser/football-pool/trunk/widgets/widget-football-pool-shoutbox.php#L127","https://plugins.trac.wordpress.org/browser/football-pool/tags/2.13.4/widgets/widget-football-pool-shoutbox.php#L127","https://plugins.trac.wordpress.org/changeset/3538628/football-pool/trunk/widgets/widget-football-pool-shoutbox.php"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:13:26.108Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/8xxx/CVE-2026-8790.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-8790","state":"PUBLISHED","datePublished":"2026-08-05T04:25:26.540Z","dateUpdated":"2026-08-05T16:19:40.108Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-05-17T19:23:29.224Z"},"containers":{"cna":{"title":"Football Pool <= 2.13.4 - Authenticated (Subscriber+) Reflected Cross-Site Scripting","descriptions":[{"lang":"en","value":"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.
