{"cve":"CVE-2026-76801","nvd":{"published":"2026-09-09T03:17:24.943","modified":"2026-09-09T15:33:47.627","status":"Deferred","description":"The FireBox – WooCommerce Popup Builder, Exit Intent Popup, Email Optin & Cart Abandonment plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 3.1.10 via the value function. This is due to a trivially bypassable regex blacklist in Executer::allowedToRun() that fails to block WordPress core functions such as wp_insert_user, update_option, and file_put_contents, combined with no sanitization of PHP condition rule values stored via the firebox_meta REST endpoint. This makes it possible for authenticated attackers, with author-level access and above, to execute code on the server. On sites upgraded from a version prior to 3.1.10, the Migrator::preserveCampaignRoleAccess() function automatically grants the edit_fireboxes and publish_fireboxes capabilities to the Author role, lowering the effective entry point to Author-level access.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-269"],"references":["https://plugins.trac.wordpress.org/browser/firebox/tags/3.1.10/Inc/Core/FB/Meta.php#L411","https://plugins.trac.wordpress.org/browser/firebox/tags/3.1.10/Inc/Core/Migrator.php#L606","https://plugins.trac.wordpress.org/browser/firebox/tags/3.1.10/Inc/Framework/Inc/Base/Conditions/Conditions/PHP.php#L36","https://plugins.trac.wordpress.org/browser/firebox/tags/3.1.10/Inc/Framework/Inc/Base/Executer.php#L231","https://plugins.trac.wordpress.org/changeset?reponame=&old=3666018%40firebox&new=3666018%40firebox"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:52:53.108888569+00:00"},"epss":{"cve":"CVE-2026-76801","score":0.00939,"percentile":0.60917,"date":"2026-11-01"},"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).
