Kubernetes Issues and Security

• 1: Kubernetes Issue Tracker
• 2: Kubernetes Security and Disclosure Information
• 3: Official CVE Feed

1 - Kubernetes Issue Tracker

To report a security issue, please follow the Kubernetes security disclosure process.

Work on Kubernetes code and public issues are tracked using GitHub Issues.

• Official list of known CVEs (security vulnerabilities) that have been announced by the Security Response Committee
• CVE-related GitHub issues

Security-related announcements are sent to the kubernetes-security-announce@googlegroups.com mailing list.

2 - Kubernetes Security and Disclosure Information

This page describes Kubernetes security and disclosure information.

Security Announcements

Join the kubernetes-security-announce group for emails about security and major API announcements.

Report a Vulnerability

We're extremely grateful for security researchers and users that report vulnerabilities to the Kubernetes Open Source Community. All reports are thoroughly investigated by a set of community volunteers.

To make a report, submit your vulnerability to the Kubernetes bug bounty program. This allows triage and handling of the vulnerability with standardized response times.

You can also email the private security@kubernetes.io list with the security details and the details expected for all Kubernetes bug reports.

You may encrypt your email to this list using the GPG keys of the Security Response Committee members. Encryption using GPG is NOT required to make a disclosure.

When Should I Report a Vulnerability?

• You think you discovered a potential security vulnerability in Kubernetes
• You are unsure how a vulnerability affects Kubernetes
• You think you discovered a vulnerability in another project that Kubernetes depends on
  • For projects with their own vulnerability reporting and disclosure process, please report it directly there

When Should I NOT Report a Vulnerability?

• You need help tuning Kubernetes components for security
• You need help applying security related updates
• Your issue is not security related

Security Vulnerability Response

Each report is acknowledged and analyzed by Security Response Committee members within 3 working days. This will set off the Security Release Process.

Any vulnerability information shared with Security Response Committee stays within Kubernetes project and will not be disseminated to other projects unless it is necessary to get the issue fixed.

As the security issue moves from triage, to identified fix, to release planning we will keep the reporter updated.

Public Disclosure Timing

A public disclosure date is negotiated by the Kubernetes Security Response Committee and the bug submitter. We prefer to fully disclose the bug as soon as possible once a user mitigation is available. It is reasonable to delay disclosure when the bug or the fix is not yet fully understood, the solution is not well-tested, or for vendor coordination. The timeframe for disclosure is from immediate (especially if it's already publicly known) to a few weeks. For a vulnerability with a straightforward mitigation, we expect report date to disclosure date to be on the order of 7 days. The Kubernetes Security Response Committee holds the final say when setting a disclosure date.

3 - Official CVE Feed

This is a community maintained list of official CVEs announced by the Kubernetes Security Response Committee. See Kubernetes Security and Disclosure Information for more details.

The Kubernetes project publishes a programmatically accessible feed of published security issues in JSON feed and RSS feed formats. You can access it by executing the following commands:

• JSON feed
• RSS feed

curl -Lv https://k8s.io/docs/reference/issues-security/official-cve-feed/index.json

curl -Lv https://k8s.io/docs/reference/issues-security/official-cve-feed/feed.xml

This feed is auto-refreshing with a noticeable but small lag (minutes to hours) from the time a CVE is announced to the time it is accessible in this feed.

The source of truth of this feed is a set of GitHub Issues, filtered by a controlled and restricted label official-cve-feed. The raw data is stored in a Google Cloud Bucket which is writable only by a small number of trusted members of the Community.
