Claude Code, a tool that uses AI to help write software, had a security flaw in versions before 2.1.2 where its bubblewrap sandboxing mechanism (a security container that isolates code) failed to protect a settings file called .claude/settings.json if it didn't already exist. This allowed malicious code running inside the sandbox to create this file and add persistent hooks (startup commands that execute automatically), which would then run with elevated host privileges when Claude Code restarted.
