Security Workflow

Security Workflow

If the report is rejected at any point, the workflow skips to Final Feedback.

  1. Reporting

    • Team members handling security issues and team leaders are required to have available and accessible public keys.
    • No initial reports should be transmitted over unencrypted or insecure channels.
  2. Report Handling

    1. Confidentiality Assurance

      If the report is located in a publicly accessible location, a Team member attempts to soft delete it (if possible, e.g. on the Community Forums) or contact the author (or other party that might help removing it temporarily).

    2. Alerting Team Members

      A Team member alerts the Team (preferably on internal Discord #staff-security channel) and provides links and/or information.

    3. Acknowledgement

      If applicable, a Team member responds to the author that their report has been acknowledged and is being processed.

  3. Internal Processing

    1. Triage and Analysis

      The vulnerability is assessed by team members handling security issues.

      A [Vulnerability Report]-prefixed staff-only thread is created for each valid vulnerability in the Development → 1.8 section, and added to the list of Security issues in the appropriate Getting 1.8.x Ready thread for an upcoming version.

      Information tracked in the opening post of the thread may include:

      • documentation:
        • a brief description (root cause, conditions, impact, vulnerability type),
        • a detailed analysis of the current codebase state and related code history,
        • links to drafts of related security advisories,
        • possible solutions,
      • metadata:
        • severity (Low / Medium / High Risk), basing on real-world impact,
        • a CVSS score,
        • a CWSS score,
        • a CVE ID (applicable CNAs: MITRE Corporation; GitHub, Inc.),
        • relevant CWE types,
        • report origin, the reporter’s details, and credit preferences.
    2. Technical Assessment Feedback

      If applicable, a Team member responds to the author and includes:

      • the triage status of each reported vulnerability (confirmed, invalid, or no fix is expected),
      • expected patch release timeline (usually the upcoming version),
      • a request for public attribution preferences and information (name and optional company/group affiliation).
    3. Remediation

      1. The development team and security team members prepare and implement measures (including code patches in git diff format and third party cooperation) that will eliminate or mitigate the vulnerabilities and prevent related threats in the future.

        Once an acceptable solution is provided, a [fix] link is added/updated in the Getting 1.8.x Ready thread.

      2. Prepared patches are verified internally.

    4. Consultation

      If applicable, Team members cooperate with the reporter to arrive with the best solution possible. During and after the solution development the patch details may be forwarded to the reporter to verify that all vulnerabilities have been properly addressed.

    5. Documentation

      • Release Metadata

        Information in the Getting * Ready thread is updated, including Additional values for version .md and the Security issues and Internal QA focus lists.

      • Security Advisory Draft

        Drafts of Security Advisories for confirmed vulnerabilities are created:

        ### Impact
        ### Details
        ### Patches
        MyBB 1.8.(...) resolves this issue with the following changes:
        - Commit:

  4. Releasing

    1. Package Verification

      Team members handling security issues verify that the release candidate QA packages contain valid patches.

    2. Release

      The final Release Candidate packages are published as official stable releases.

    3. Advisory Publication

      1. Relevant security advisories are published.
      2. If applicable, CVE update requests are submitted to relevant CNAs.
    4. Attribution Verification

      The vulnerability information and attribution credits are verified (Release Blog Post, Release Notes).

  5. Final Feedback

    If applicable, a team member responds to the original reporter and includes:

    • version numbers of products containing related patches,
    • links to related publications with acknowledgements (Release Blog Post, Release Notes),
    • links to related security advisories,
    • related CVE IDs.
