The psub function in fish (aka fish-shell) 1.16.0 before 2.1.1 does not properly create temporary files, which allows local users to execute arbitrary commands via a temporary file with a predictable name.

Security readout for executives and security teams

CVE-2014-2906 is a local-user risk in older fish-shell versions. A flaw in the psub function used predictable temporary file names, creating an opportunity for another local user to influence execution. The issue matters most on shared systems, build hosts, or developer machines where fish-shell is installed and multiple users have access. Exposure is likely limited to systems running fish-shell 1.16.0 before 2.1.1, especially shared Unix-like hosts where untrusted or less-trusted local users can run processes. Single-user desktops have lower practical exposure, but outdated developer images or legacy servers should still be checked. Treat this as a targeted legacy cleanup item, not an emergency internet-facing incident. Prioritize shared systems and old developer or build environments because exploitation requires local access but could affect command execution under user workflows. Mitigation focus: Upgrade fish-shell to version 2.1.1 or later.; Check current vendor or distribution package guidance for backported fixes.; Prioritize shared hosts and developer systems with multiple local users..
