Ideas + Bugs Highlights Prompt-Injection Risks
Ideas + Bugs is Pieter Levels’ public feedback board for collecting bug reports and feature requests across his products. A recent discussion highlights how feeding that untrusted user content into an AI coding agent could smuggle malicious instructions into seemingly routine pull requests.
- –Indirect prompt injections can hide instructions inside bug reports or feature requests.
- –Human PR approval is not foolproof when attackers disguise backdoors as ordinary fixes or use cryptic code.
- –Safer designs isolate the agent, restrict GitHub permissions, block production credentials and network access, and treat all user text as untrusted data.
- –Read-only intake plus deterministic tests, security scanning, provenance checks, and careful diff review meaningfully reduce—but do not eliminate—the risk.
- –The concern aligns with broader warnings that AI coding agents can be manipulated through issue bodies, PR descriptions, comments, and repository content.
