customize-sdk-hooks

The document accurately explains how to implement SDK hooks and provides useful examples (User-Agent injection, HMAC signing, telemetry). There is no intrinsic malicious code in the artifact, but the hook mechanism gives implementers the ability to access secrets and make arbitrary outbound requests — exactly the capabilities an attacker would exploit to exfiltrate data. The primary security concern is governance: unreviewed or malicious hooks can leak sensitive data. Apply strict review, runtime restrictions (endpoint allowlists, redaction), and monitoring when allowing custom hooks in production.
