CVE-2026-1251

SupportCandy – Helpdesk & Customer Support Ticket System <= 3.4.4 - Authenticated (Subscriber+) Insecure Direct Object Reference

The SupportCandy – Helpdesk & Customer Support Ticket System plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.4.4 via the 'add_reply' function due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with subscriber-level access and above, to steal file attachments uploaded by other users by specifying arbitrary attachment IDs in the 'description_attachments' parameter, re-associating those files to their own tickets and removing access from the original owners.

CVE-2026-0683

SupportCandy – Helpdesk & Customer Support Ticket System <= 3.4.4 - Authenticated (Subscriber+) SQL Injection via Number Field Filter

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.
