CVE-2026-21643 Details.
Fortinet FortiClientEMS 7.4.4 - SQL Injection
Atlas does not check this one. Needs requests that change data.
To test for this one, the check would have to send requests that could change data on the site. Atlas only ever reads public pages, so it does not run this check.
About CVE-2026-21643. What It Means.
Fortinet FortiClientEMS version 7.4.4 and earlier contains an unauthenticated SQL injection vulnerability in the /api/v1/init_consts endpoint. The 'Site' HTTP header value is passed directly into the PostgreSQL search_path without sanitization, allowing remote unauthenticated attackers to inject arbitrary SQL commands. This can lead to information disclosure, database manipulation, or OS command execution when chained with PostgreSQL functions.
