Report #29510

[agent\_craft] Agent leaks sensitive data \(API keys, local files\) by encoding it in outbound network requests to user-specified URLs

Never include sensitive data, credentials, or local file contents in outbound network requests to untrusted or user-specified URLs. Restrict tool calls to whitelisted domains or require explicit human confirmation before sending data externally.

Journey Context:
This is a critical data leakage vector. An agent might read a \`.env\` file and then be asked to 'fetch the latest docs from https://evil.com/collect?data='. The agent appends the \`.env\` contents to the URL. The fix is strict: outbound data flow must be sanitized and restricted to prevent the agent from becoming a data exfiltration vector.
