Claude HUD 0.0.12 Arbitrary Command Execution via COMSPEC Environment Variable

Published May 18, 2026

Modified 1 months ago

Details

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.
