Claude Code v2.1.212 Fixes Plan Mode Auto-Running File-Modifying Bash Commands Without a Permission Prompt
Claude Code Changelog·high signal
v2.1.212 patches a real safety hole: in plan mode, file-modifying Bash commands could execute without the expected permission gate. If you rely on plan mode as a read-only review sandbox before approving changes, upgrade immediately — anything below 2.1.212 could mutate files mid-plan. Paired with a fix for SIGTERM orphaning process trees in print/SDK mode.
