CVE-2026-94585· CVE.org (no NVD analysis yet)· CNA brocade

An authentication bypass vulnerability exists in the web management interface of Brocade Fabric OS versions before 9.2.2d running on the MXG

Noroxi assessment

Priority: Monitor (action score 30/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.18% (FIRST EPSS).
  • Someone on the same network segment can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: Brocade Fabric OS 9.2.2d.

Low priority for now. Upgrade to Brocade Fabric OS 9.2.2d or later.

Primary sources: NVD · CVE.org · FIRST EPSS

An authentication bypass vulnerability exists in the web management interface of Brocade Fabric OS versions before 9.2.2d running on the MXG610 platform. An unauthenticated, network-adjacent attacker can exploit an unauthenticated endpoint within the Single Sign-On (SSO) workflow to gain administrative access to the device management interface.
