{"id":"CVE-2026-0683","state":"PUBLISHED","title":"SupportCandy – Helpdesk & Customer Support Ticket System <= 3.4.4 - Authenticated (Subscriber+) SQL Injection via Number Field Filter","description":"The SupportCandy – Helpdesk & Customer Support Ticket System plugin for WordPress is vulnerable to SQL Injection via the Number-type custom field filter in all versions up to, and including, 3.4.4. This is due to insufficient escaping on the user-supplied operand value when using the equals operator and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Subscriber-level access and above (customers), to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.","publishedAt":"2026-01-31T05:52:46.922Z","updatedAt":"2026-04-08T17:13:40.679Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["psmplugins SupportCandy – Helpdesk & Customer Support Ticket System"],"affected":[{"vendor":"psmplugins","product":"SupportCandy – Helpdesk & Customer Support Ticket System","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.4.4","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/a7856d0f-bc7d-436c-968c-631fd6a686ab?source=cve","https://plugins.trac.wordpress.org/browser/supportcandy/tags/3.4.4/includes/admin/tickets/class-wpsc-ticket-list.php#L1265","https://plugins.trac.wordpress.org/browser/supportcandy/tags/3.4.4/includes/admin/tickets/class-wpsc-ticket-list.php#L1288","https://plugins.trac.wordpress.org/browser/supportcandy/tags/3.4.4/includes/custom-field-types/class-wpsc-cf-number.php#L371","https://plugins.trac.wordpress.org/changeset/3448376/"],"weaknesses":["CWE-89"],"ingestedAt":"2026-10-29T20:10:13.529Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/0xxx/CVE-2026-0683.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-0683","state":"PUBLISHED","datePublished":"2026-01-31T05:52:46.922Z","dateUpdated":"2026-04-08T17:13:40.679Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-01-07T18:31:17.181Z"},"containers":{"cna":{"title":"SupportCandy – Helpdesk & Customer Support Ticket System <= 3.4.4 - Authenticated (Subscriber+) SQL Injection via Number Field Filter","descriptions":[{"lang":"en","value":"The SupportCandy – Helpdesk & Customer Support Ticket System plugin for WordPress is vulnerable to SQL Injection via the Number-type custom field filter in all versions up to, and including, 3.4.4.
