CVE-2026-13262

What is known

The Majestic Support – The Leading-Edge Help Desk & Customer Support Plugin plugin for WordPress is vulnerable to generic SQL Injection via the 'val' parameter in all versions up to, and including, 1.1.9 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. Exploitation requires a valid 'get-smart-reply' nonce, which any Subscriber-level user can obtain by creating a ticket via the public frontend and visiting the resulting ticket detail page, making this effectively exploitable by any authenticated user.

Business impact

Successful exploitation of CVE-2026-13262, a medium vulnerability (CVSS 6.5) affecting the affected product, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.

Recommended administrator action

Confirm whether the affected product is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
