In this post, we explore how a simple website summary request hijacks Claude Code Opus 5 in Auto Mode and achieves code execution with 60-80% attack success rate using a small sample size. This is interesting because a third-party evaluation commissioned by Anthropic showed a 0.00% prompt injection attack success rate for Opus 5 in Auto Mode. Auto Mode Is Now the Default in Claude Code Auto Mode replaces human approval prompts with a safety classifier. Since mid-August it is the default starting mode for Claude Code.
