Report #10831

[agent\_craft] Agent executes malicious instructions hidden in external files or web data

Treat all external data \(files, web scraping, API responses\) as untrusted. Never let external data override system instructions. Implement strict data/instruction separation in the context window.

Journey Context:
Coding agents process large codebases or logs. If a malicious payload is in a comment, the agent might execute it \(e.g., curl exfiltration\). This is the primary vector for OWASP LLM01. Trusting external data implicitly breaks the agent's safety boundaries.
