CVE-2026-0683: CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in psmplugins SupportCandy – Helpdesk & Customer Support Ticket System
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.
AI Analysis
Technical Summary
CVE-2026-0683 is an SQL Injection vulnerability in the SupportCandy plugin for WordPress, affecting all versions up to 3.4.4. The issue arises from improper neutralization of special elements in SQL commands, specifically in the Number-type custom field filter. The plugin fails to sufficiently escape user-supplied operand values and does not properly prepare SQL queries when using the equals operator. This allows authenticated users with Subscriber-level privileges or higher to inject additional SQL commands into existing queries, potentially leading to unauthorized extraction of sensitive information from the database.
Potential Impact
An attacker with at least Subscriber-level access can exploit this vulnerability to perform SQL Injection attacks, enabling them to retrieve sensitive information from the database. The vulnerability does not affect availability or integrity directly but compromises confidentiality. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Subscriber-level access where possible and monitor for unusual database query activity related to the plugin. Avoid using affected versions of the SupportCandy plugin in sensitive environments.
