How do I detect CVE-2026-94579 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-2026-94579 if there is no patch (or I can't update yet)?

Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.

Is CVE-2026-94579 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-94579 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.

Description

An OS command injection vulnerability exists in the PAM (Pluggable Authentication Module) session cleanup routines during SSH session termination on Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. An authenticated user authenticating via an external directory or AAA service whose username or profile identifier contains shell metacharacters can trigger arbitrary command execution with root privileges when their remote SSH session closes.
