What is CVE-2026-20003?

A security flaw has been identified in the REST API of Cisco Secure FMC Software that may allow an authenticated remote attacker to execute SQL injection attacks. This vulnerability arises from inadequate input validation of user-supplied data. By sending specially crafted requests to the affected system, an attacker with valid user credentials—including roles such as Administrator, Security Approver, Intrusion Admin, Access Admin, or Network Admin—can exploit this weakness. Successful exploitation may enable the attacker to gain unauthorized read access to sensitive database information and files located on the underlying operating system.
