Claude HUD through 0.0.12, patched in commit 234d9aa, contains a command injection vulnerability that allows local attackers to execute arbitrary commands by manipulating the COMSPEC environment variable. Attackers can set COMSPEC to an arbitrary binary path before claude-hud performs its version check, causing execFile() to execute the attacker-supplied executable with cmd.exe arguments, resulting in arbitrary code execution on Windows systems.
AnalysisAI
Local privilege code execution in jarrodwatts/claude-hud through version 0.0.12 on Windows allows authenticated local users to run arbitrary executables by setting the COMSPEC environment variable before the tool's version check, where execFile() launches whatever binary COMSPEC points to with cmd.exe-style arguments. The flaw is tracked as CWE-427 (Uncontrolled Search Path Element) and was reported by VulnCheck; no public exploit identified at time of analysis, but the upstream commit 234d9aa makes the fix mechanics straightforward to reverse-engineer.

RemediationAI
Within 24 hours: Inventory all Windows systems running claude-hud versions ≤0.0.12; restrict local user access to these systems if immediate patching is not feasible. Within 7 days: Update all instances to the latest available patched version per jarrodwatts/claude-hud vendor advisory. …
