CVE-2026-8790

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 `` 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.</p></div> <div class="ds"><h2>Affected Platforms</h2><div><span class="ptag">Unknown</span></div></div> <div class="ds"><h2>Weakness Type</h2><p>CWE-79</p></div> <div class="ds"><h2>References</h2><ul style="list-style:none;display:flex;flex-direction:column;gap:0.4rem;"><li><a href="https://plugins.trac.wordpress.org/browser/football-pool/tags/2.13.4/widgets/widget-football-pool-shoutbox.php#L127" target="_blank" rel="noopener">https://plugins.trac.wordpress.org/browser/football-pool/tags/2.13.4/widgets/wid…</a></li><li><a href="https://plugins.trac.wordpress.org/browser/football-pool/tags/2.13.4/widgets/widget-football-pool-shoutbox.php#L142" target="_blank" rel="noopener">https://plugins.trac.wordpress.org/browser/football-pool/tags/2.13.4/widgets/wid…</a></li><li><a href="https://plugins.trac.wordpress.org/browser/football-pool/tags/2.13.4/widgets/widget-football-pool-shoutbox.php#L84" target="_blank" rel="noopener">https://plugins.trac.wordpress.org/browser/football-pool/tags/2.13.4/widgets/wid…</a></li><li><a href="https://plugins.trac.wordpress.org/browser/football-pool/trunk/widgets/widget-football-pool-shoutbox.php#L127" target="_blank" rel="noopener">https://plugins.trac.wordpress.org/browser/football-pool/trunk/widgets/widget-fo…</a></li><li><a href="https://plugins.trac.wordpress.org/browser/football-pool/trunk/widgets/widget-football-pool-shoutbox.php#L142" target="_blank" rel="noopener">https://plugins.trac.wordpress.org/browser/football-pool/trunk/widgets/widget-fo…</a></li><li><a href="https://plugins.trac.wordpress.org/browser/football-pool/trunk/widgets/widget-football-pool-shoutbox.php#L84" target="_blank" rel="noopener">https://plugins.trac.wordpress.org/browser/football-pool/trunk/widgets/widget-fo…</a></li></ul></div> </div> <div class="wrap"><footer><span>© 2025 Artfical DT</span><div style="display:flex;gap:1.2rem;"><a href="/privacy?lang=en">Privacy Policy</a><a href="https://artfical.com">artfical.com</a></div></footer></div> <script src="/__defend3r/badge.js" defer data-defend3r="1" data-position="br"></script></body></html>
