{"id":"CVE-2026-19806","state":"PUBLISHED","title":"Support Genix <= 1.4.52 - Authenticated (Subscriber+) Authentication Bypass to Administrator Account Takeover via 'p' Parameter Forged Guest Token","description":"The Support Genix – Helpdesk, AI Chatbot, Knowledge Base & Customer Support Ticketing System plugin for WordPress is vulnerable to Authentication Bypass leading to Administrator Account Takeover in all versions up to, and including, 1.4.52 via the `guest_ticket_login()` function and its `p` parameter. This is due to the site-wide AES-256-CBC encryption key being derived from only three two-digit `wp_rand(10, 99)` values and a Unix timestamp via `md5()` — yielding approximately 19.5 bits of entropy — combined with a deterministic IV derived from the password, no authentication tag on the ciphertext, and no capability check, nonce, or session validation on the publicly reachable `/sgnix/?p=<token>` endpoint. This makes it possible for authenticated attackers, with subscriber-level access and above, who can obtain a single legitimate guest ticket token as a known-plaintext oracle and bound the plugin activation timestamp, to exhaust the ~729,000-candidate keyspace entirely offline, recover the site-wide encryption key, and forge a self-consistent `{ticket_id, ticket_user}` token targeting any administrator-owned ticket. Submitting the forged token to the unprotected endpoint causes `wp_set_auth_cookie()` to be called for that administrator, granting the attacker full administrative access to the WordPress site.","publishedAt":"2026-09-01T04:27:49.216Z","updatedAt":"2026-09-02T17:53:01.887Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["devitemsllc Support Genix – Helpdesk, AI Chatbot, Knowledge Base & Customer Support Ticketing System"],"affected":[{"vendor":"devitemsllc","product":"Support Genix – Helpdesk, AI Chatbot, Knowledge Base & Customer Support Ticketing System","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.4.52","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/188f7c1d-e8ad-4114-9aa4-c3e8b51c5f2c?source=cve","https://plugins.trac.wordpress.org/browser/support-genix-lite/tags/1.4.51/modules/Apbd_wps_settings.php#L748","https://plugins.trac.wordpress.org/browser/support-genix-lite/tags/1.4.51/modules/Apbd_wps_settings.php#L152","https://plugins.trac.wordpress.org/browser/support-genix-lite/tags/1.4.51/libs/Apbd_Wps_EncryptionLib.php#L27","https://plugins.trac.wordpress.org/browser/support-genix-lite/tags/1.4.51/core/secondary_helper.php#L754","https://plugins.trac.wordpress.org/browser/support-genix-lite/tags/1.4.51/models/database/Mapbd_wps_ticket.php#L457","https://plugins.trac.wordpress.org/browser/support-genix-lite/tags/1.4.50/modules/Apbd_wps_settings.php#L748","https://plugins.trac.wordpress.org/browser/support-genix-lite/tags/1.4.50/modules/Apbd_wps_settings.php#L152","https://plugins.trac.wordpress.org/browser/support-genix-lite/tags/1.4.50/libs/Apbd_Wps_EncryptionLib.php#L27","https://plugins.trac.wordpress.org/browser/support-genix-lite/tags/1.4.50/core/secondary_helper.php#L754","https://plugins.trac.wordpress.org/browser/support-genix-lite/tags/1.4.50/models/database/Mapbd_wps_ticket.php#L457","https://plugins.trac.wordpress.org/changeset?reponame=&old=3668350%40support-genix-lite&new=3668350%40support-genix-lite"],"weaknesses":["CWE-287"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/19xxx/CVE-2026-19806.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-19806","state":"PUBLISHED","datePublished":"2026-09-01T04:27:49.216Z","dateUpdated":"2026-09-02T17:53:01.887Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-08-13T21:00:07.082Z"},"containers":{"cna":{"title":"Support Genix <= 1.4.52 - Authenticated (Subscriber+) Authentication Bypass to Administrator Account Takeover via 'p' Parameter Forged Guest Token","descriptions":[{"lang":"en","value":"The Support Genix – Helpdesk, AI Chatbot, Knowledge Base & Customer Support Ticketing System plugin for WordPress is vulnerable to Authentication Bypass leading to Administrator Account Takeover in all versions up to, and including, 1.4.52 via the `guest_ticket_login()` function and its `p` parameter.
