Prompt injection bypasses Claude model's commit message generation

By PulseAugur Editorial · [1 sources] ·

A developer tested prompt injection vulnerabilities against their commit message generation tool, which uses Anthropic's Claude model. Out of ten custom payloads, seven successfully bypassed the system prompt's constraints, leading to unintended outputs like added co-author lines or AI attribution. Classic prompt injection techniques, such as "ignore instructions" or "fake system tag," were ineffective, but payloads requesting minor exceptions embedded within the diff text were successful. AI

IMPACT Highlights potential vulnerabilities in LLM-based tools, emphasizing the need for robust input validation and security measures.

    7 of 10 Prompt-Injection Payloads Broke My Commit-Message Generator's System Prompt

    <p>Every few days someone on here posts a number from a prompt-injection test they ran against their agent, and every time I read it I wonder how it would hold up against mine. I have a small, boring, perfect target sitting in my own repo: a tool called <code>generate_commit_mess…
