{"id":"CVE-2026-19946","state":"PUBLISHED","title":"Awesome Support <= 6.3.9 - Missing Authorization to Authenticated (Subscriber+) Arbitrary User Denial via 'user_id' Parameter","description":"The Awesome Support plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 6.3.9. This is due to a missing capability check on the wpas_do_mr_deny_user() function, which unlike its counterpart wpas_do_mr_activate_user() does not enforce current_user_can('edit_users') or current_user_can('edit_user', $user_id), relying solely on a nonce that is not scoped to the target user. This makes it possible for authenticated attackers, with subscriber-level access and above, to set the mr_user_denied flag on any user account — including administrators — permanently blocking their moderated activation and dispatching a denial notification email to the victim.","publishedAt":"2026-09-09T05:31:03.643Z","updatedAt":"2026-09-11T20:19:14.539Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["awesomesupport Awesome Support – WordPress HelpDesk & Support Plugin"],"affected":[{"vendor":"awesomesupport","product":"Awesome Support – WordPress HelpDesk & Support Plugin","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"6.3.9","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/208f9475-446c-4cf1-9d70-a845cf9b3005?source=cve","https://plugins.trac.wordpress.org/browser/awesome-support/tags/6.3.9/includes/functions-user.php#L1731","https://plugins.trac.wordpress.org/browser/awesome-support/tags/6.3.9/includes/functions-actions.php#L25","https://plugins.trac.wordpress.org/browser/awesome-support/tags/6.3.9/includes/functions-user.php#L1650","https://plugins.trac.wordpress.org/log/awesome-support/"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/19xxx/CVE-2026-19946.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-19946","state":"PUBLISHED","datePublished":"2026-09-09T05:31:03.643Z","dateUpdated":"2026-09-11T20:19:14.539Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-08-15T16:51:37.070Z"},"containers":{"cna":{"title":"Awesome Support <= 6.3.9 - Missing Authorization to Authenticated (Subscriber+) Arbitrary User Denial via 'user_id' Parameter","descriptions":[{"lang":"en","value":"The Awesome Support plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 6.3.9.
