Doc Text:
A flaw was found in ISPConfig. A remote API user with low-privilege permissions can exploit an authenticated SQL injection vulnerability in the Remote API. This occurs because the `primary_id` parameter is directly used in SQL queries without proper validation. An attacker can leverage this to delete or modify database records across all tenants and extract sensitive data, such as password hashes and client records.

Description OSIDB Bzimport 2026-08-19 17:56:01 UTC 
ISPConfig contains an authenticated SQL injection vulnerability in the Remote API. The primary_id parameter passed to delete and update API methods is concatenated directly into SQL WHERE clauses without integer casting or parameterized query binding. The built-in SQL injection scanner does not block quote-free boolean payloads and does not reject requests in its default configuration. A remote API user holding any single low-privilege function permission can inject arbitrary SQL to delete or modify records across all tenants in the control panel database and extract arbitrary data via blind boolean inference, including password hashes and client records.
