High Injection

CVE-2026-20344 — Cisco Secure Firewall Management Center Software SQL Injection Vulnerability

A vulnerability in the web-based management interface of Cisco Secure FMC Software could allow an authenticated, remote attacker to perform a SQL injection attack against an affected device. To exploit this vulnerability, the attacker must have a valid account on the device with the role of Security Approver, Access Admin, or Network Admin. This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending a crafted HTTP request to the web-based management interface of an affected device. A successful exploit could allow the attacker to obtain any data from the database, obtain the session credentials of an authenticated Administrator, and take actions with administrative privileges on the affected device.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

Technical severity (high)+6

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.
