CVE-2026-20001 — Cisco Secure Firewall Management Center Software SQL Injection Vulnerabilities

A vulnerability in the REST API of Cisco Secure FMC Software could allow an authenticated, remote attacker to conduct SQL injection attacks on an affected system. This vulnerability is due to inadequate validation of user-supplied input. An attacker could exploit this vulnerability by sending crafted requests to an affected device. A successful exploit could allow the attacker to obtain read access to the database and read certain files on the underlying operating system. To exploit this vulnerability, the attacker would need valid user credentials with any of the following roles: Administrator Security approver Access admin Network admin

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
  • EPSS 0.3% (30-day exploitation probability)+4
  • Technical severity (medium)+3

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.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Cisco Cisco Secure Firewall Management Center (FMC)).
  2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  3. Search available logs for exploit probes matching the vulnerability class (injection), errors and authentication anomalies.
