No fixed release is recorded for CVE-2026-94577 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.

How do I detect CVE-2026-94577 in my code and dependencies?

Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).

How do I mitigate CVE-2026-94577 if there is no patch (or I can't update yet)?

Close the privilege gap rather than the entry point: audit which accounts, roles and service identities can reach the affected operation, drop the component to the least privilege it actually needs, and review file and directory permissions created by earlier installs — a default left in place is what makes this reachable.

Is CVE-2026-94577 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-94577 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2026-94577?

CVE-2026-94577 has an EPSS (Exploit Prediction Scoring System) score of 0.1%, placing it in the 1th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2026-94577?

Description

A privilege escalation vulnerability exists in the internal Command-Line Interface (CLI) authorization handling mechanism of Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. An authenticated user or local process that can manipulate the process execution environment can bypass Role-Based Access Control (RBAC) validation checks. Successful exploitation allows an attacker to elevate privileges to root
