CVE-2026-54699

Host command execution via unescaped WSL URL

Published Jun 24, 2026 · Updated Jun 24, 2026

OS command injection in affected Warp WSL builds allows attackers to run commands on the Windows host through a malicious terminal link. The WSL URL-opening fallback passes the raw terminal-derived URL to cmd.exe /c start without parsing, scheme restrictions, or metacharacter escaping. Exploitation requires a user to open the link while wslview is unavailable and WARP_FORCE_WSL_BROWSER is unset; native platforms are unaffected.
