Authenticated SQL Injection in Fortinet FortiDDoS-F REST API
CVE-2026-39815 is an authenticated SQL injection vulnerability in the REST API of Fortinet FortiDDoS-F affecting versions 7.2.1 through 7.2.2. The flaw is caused by improper neutralization of special elements used in SQL commands, allowing user-supplied input from crafted HTTP API requests to be incorporated into backend SQL queries without proper sanitization or parameterization. According to the available content, exploitation requires a valid authenticated session using the product’s bearer-token-based API authentication. A successful attacker can execute arbitrary SQL queries against the appliance’s backend database. The specific vulnerable endpoint or parameter has not been publicly disclosed in the provided material. Fortinet fixed the issue in version 7.2.3 and later.
