This makes it possible for authenticated attackers, with custom-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires that an administrator has explicitly granted the 'Create and Update Modules' (hustle_create / hustle_edit_module) capability to the attacker's role via the plugin's own Settings → Permissions feature; this delegation is not enabled by default.","severity":"medium","score":6.4,"published":"2026-10-28T06:45:18.336Z","modified":"2026-10-28T16:09:34.692Z","withdrawn":false,"knownExploited":false,"affected":[],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/a3ed1a2a-f9d5-4f34-8a8e-583ea7226df8?source=cve","https://plugins.trac.wordpress.org/browser/wordpress-popup/tags/7.8.14.3/inc/front/hustle-module-renderer.php#L181","https://plugins.trac.wordpress.org/browser/wordpress-popup/tags/7.8.14.3/inc/front/hustle-module-renderer.php#L163","https://plugins.trac.wordpress.org/browser/wordpress-popup/tags/7.8.14.3/inc/hustle-module-model.php#L569","https://plugins.trac.wordpress.org/browser/wordpress-popup/tags/7.8.14.3/inc/hustle-modules-common-admin-ajax.php#L49","https://plugins.trac.wordpress.org/browser/wordpress-popup/tags/7.8.14.3/inc/front/hustle-module-front.php#L917","https://plugins.trac.wordpress.org/changeset/3758337/wordpress-popup/trunk/inc/front/hustle-module-renderer.php"],"sources":[{"name":"CVE","id":"CVE-2026-107710","modified":"2026-10-28T16:09:34.692Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-107710"}],"assessments":[{"source":"Wordfence","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":6.4}],"sourceAffected":[],"kev":{"status":"not-listed","checkedAt":"2026-10-28T23:20:36.067Z"},"coverage":[{"source":"NVD","status":"available","checkedAt":"2026-10-28T09:30:33.149Z","attemptedAt":"2026-10-28T09:30:33.149Z"},{"source":"GHSA","status":"no-result","checkedAt":"2026-10-28T09:30:32.942Z","attemptedAt":"2026-10-28T09:30:32.942Z"},{"source":"EUVD","status":"available","checkedAt":"2026-10-28T09:30:33.032Z","attemptedAt":"2026-10-28T09:30:33.032Z"},{"source":"EPSS","status":"no-result","checkedAt":"2026-10-28T09:30:33.199Z","attemptedAt":"2026-10-28T09:30:33.199Z"}],"evidence":[{"source":"ENISA EUVD","id":"EUVD-2026-111605","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-111605","modified":"Oct 28, 2026, 6:45:18 AM","score":6.4,"vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","checkedAt":"2026-10-28T09:30:33.032Z"},{"source":"NVD","id":"CVE-2026-107710","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-107710","modified":"2026-10-28T07:16:43.810","score":6.4,"vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","checkedAt":"2026-10-28T09:30:33.149Z"}]}
