Webpack Security Incident Response Plan

This document defines how the Webpack project responds to security incidents.
It is intended for maintainers and contributors who may need to coordinate a response.

Scope

This plan applies to incidents such as:

• Vulnerabilities in Webpack core modules or official tools (e.g., webpack-cli, webpack-dev-server).
• Dependency vulnerabilities that impact Webpack users.
• Premature public disclosure of a vulnerability.
• Account compromise or supply-chain risks affecting the project.

Communication Channels

• Private & Preferred: GitHub Security Advisories.
• Email: webpack-security@openjsf.org.
• Public: GitHub releases, changelog, and advisories (after fix is available).

Incident Response Workflow

1. Report Received

• Reports should be submitted via GitHub Security Advisories (preferred) or private email.
• Acknowledgment timelines:
  • Standard reports: within 30 days.
  • Zero-day or critical vulnerabilities: within 7 days.

2. Triage & Assessment

• Validate whether the report is security-related.
• Classify severity (critical, high, medium, low).
• Determine impact and scope (affected versions, configurations, or environments).

3. Containment & Private Fix Development

• Create a private working group (e.g., GitHub private fork or draft advisory).
• Explore temporary mitigations if immediate patching is not feasible.
• Maintain confidentiality during the process.

4. Fix & Testing

• Develop and review a fix privately.
• Add regression tests where applicable.
• Backport fixes to supported major versions if relevant.

5. Release

• Publish a patched release.
• Publish a security advisory simultaneously, including:
  • Description of the issue.
  • Impacted versions.
  • Severity rating.
  • Mitigation or upgrade steps.
