What happened
A blog post details security failures in Omarchy 4.0, a Linux distro promoted by DHH, including bash injection via video titles and notifications capable of running arbitrary bash commands. The author attributes these to AI-generated bash scripts processing untrusted input without review, arguing the project's security team announcements are marketing that mask fundamentally insecure development practices.
Why it matters
If you are using AI-generated bash or shell scripts to handle user-controlled input (titles, notifications, filenames), you are likely shipping the same class of vulnerability Omarchy did. Audit any pipeline where untrusted strings reach bash execution and add input validation or switch to a language with proper escaping before someone else finds it.
Discussion angle
Where is the line between 'AI-assisted coding is fine if you review it' and 'AI-generated bash processing untrusted input is never safe regardless of review' — and what does that mean for vibe coders shipping tools that touch the shell?
