{"cve":"CVE-2026-8790","nvd":{"published":"2026-08-05T06:16:40.810","modified":"2026-08-12T21:00:37.147","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-79"],"references":["https://plugins.trac.wordpress.org/browser/football-pool/tags/2.13.4/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#L142","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/trunk/widgets/widget-football-pool-shoutbox.php#L142"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:10.050265369+00:00"},"epss":{"cve":"CVE-2026-8790","score":0.00389,"percentile":0.32993,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
