CVE-2026-51190 [CRITICAL] – The “s init” command in Serverless-Devs @serverless-devs/s

The “s init” command in Serverless-Devs @serverless-devs/s <= 3.1.11 passes unsanitized user input to child_process.spawn() with shell: true. A URL ending in ".git" bypasses the only input check, allowing OS command injection when a user runs "s init" with an attacker-controlled argument.
