# [Vulnerability type] in [feature] allows [impact] ## Summary Briefly explain the affected security boundary, the attack, and the demonstrated impact. ## Program and asset - Program: - Affected asset: - Endpoint or feature: - Tested on: - Account or role used: ## Severity - Suggested severity: - CVSS vector, if required: - Severity rationale: Explain exploitability and business impact. Do not rely on the score alone. ## Prerequisites List the access, role, data, or application state needed before reproduction. ## Steps to reproduce 1. Sign in as `[role/account]`. 2. Navigate to `[feature]`. 3. Send the following request: ```http METHOD /path HTTP/1.1 Host: target.example Authorization: [redacted] Content-Type: application/json {} ``` 4. Change `[specific value]` to `[test value]`. 5. Observe `[result]`. ## Observed result State exactly what happened and include the smallest evidence needed to verify it. ## Expected result Describe the authorization, validation, isolation, or other control that should have blocked the action. ## Impact Explain what an attacker can achieve, which users or data are affected, and the realistic limits of the demonstrated attack. ## Evidence - Request and response: - Screenshot or recording: - Callback or log evidence: - Negative control: Remove tokens, personal data, and unrelated secrets before submission. ## Remediation Describe the root-cause fix first. Add defense-in-depth measures separately. ## Retest guidance List the original request, obvious bypasses, adjacent endpoints, roles, and state transitions that should be checked after remediation.
