AI-suggested

Until an official fix is available, avoid running the 's init' command with untrusted input, especially URLs ending in '.git'.

Description

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.
