Detailed Explanation

Responsible Disclosure in Release Notes

When a security researcher reports a vulnerability through responsible disclosure, the release notes for the fix need to balance transparency with responsible timing.

Coordinated Disclosure Timeline

Day 0    — Vulnerability reported privately
Day 1-3  — Acknowledge receipt, begin investigation
Day 7    — Confirm vulnerability, begin developing fix
Day 14   — Fix ready, tested across supported versions
Day 15   — Coordinate disclosure date with reporter
Day 21   — Release fix, publish advisory (CVE if applicable)
Day 28+  — Publish full technical details

## [2.4.1] - 2026-02-28

### Security

- **HIGH (CVE-2026-XXXXX):** Fix authentication bypass in API key
  validation. Requests with malformed API keys could bypass rate
  limiting and access protected endpoints without valid
  credentials. Affects v2.2.0 through v2.4.0.

  **Severity:** CVSS 8.1 (High)
  **Affected versions:** 2.2.0 - 2.4.0
  **Fix:** Strict API key format validation before processing
  **Credit:** Reported by Jane Smith (@janesmith) via our
  security bug bounty program

  See [Security Advisory SA-2026-001](link) for full details.

What to Include

Severity and CVE — use CVSS scoring for consistency
Affected versions — exact range
Brief description — vulnerability type without exploit details
Credit — always credit the reporter (with permission)
Link to advisory — for users who need more details

What NOT to Include

Proof-of-concept exploit code
Exact payload that triggers the vulnerability
Internal investigation details
Names of affected customers

Multi-Version Backport

When the fix is backported to multiple release branches, document all fixed versions:

Fixed in: v2.4.1, v2.3.5, v2.2.8 (LTS)

This helps users on older supported versions find the right update.

Use Case

Publishing security fixes that were discovered through a responsible disclosure program, where the release notes must properly credit the reporter while avoiding information that could enable exploitation of unpatched systems.
