Direct answer
Keep the original evidence in approved restricted storage and share a minimized version that shows the affected identity, object, action and result without exposing secrets or unrelated data. Record what was removed and preserve a traceable reference.
Define the minimum proof
For a cross-account invoice finding, the reviewer needs to see the caller, the separate test object's owner, the action and the unauthorized response. A synthetic invoice identifier and redacted response can establish the boundary without copying a real customer's full record.

Remove unnecessary secrets
Review request headers, cookies, bearer tokens, URL query strings, account identifiers and response bodies before sharing. Mask values consistently enough to distinguish the two test accounts. Never include a working password or access token as reproduction evidence.
- Use synthetic fixtures where available.
- Keep originals under access control and retention policy.
- Label redactions and record a restricted evidence reference.
Protect reproducibility
Describe how an authorized reviewer can recreate a test with fresh credentials and owned fixtures. A heavily edited screenshot alone may omit the request context; pair it with the method, expected result and observation. Do not claim impact beyond what the preserved evidence supports.

Choose the right audience
A developer, executive and external provider may need different levels of detail. Provide each the minimum necessary summary and transfer it using the organization's approved channel. Follow contractual retention and deletion requirements.
Assessment limits
Redaction can remove details needed for diagnosis, while insufficient redaction can disclose sensitive data. Agree evidence handling and access before testing.
Frequently asked questions
Should all response data be removed?
Retain the minimum needed to demonstrate the issue using safe fixtures; keep originals restricted when the authorized investigation requires them.
Can credentials be included to make reproduction easier?
No. Provide instructions for authorized users to create or obtain their own test credentials securely.
