CVE-2026-20316 MEDIUM POC KEV THREAT NEWS This Month

Hardcoded static credentials in Cisco Secure Firewall Management Center (FMC) Software allow an unauthenticated remote attacker to log in to the web interface using a built-in low-privileged account and access sensitive data. The flaw affects an extensive range of FMC versions from 7.0.0 through 10.0.1 and is rooted in CWE-259 (Use of Hard-coded Password). Cisco has self-elevated the Security Impact Rating to High - despite a CVSS 5.3 Medium score - explicitly because this credential foothold can be chained with other FMC vulnerabilities to escalate privileges, making the real-world risk materially higher than the base score implies. No public exploit or CISA KEV listing has been confirmed at time of analysis.
