Verify that all container images in the attestation are in the release file:

RELEASE_FILE=https://infra.tekton.dev/tekton-releases/pipeline/previous/v1.11.1/release.yaml
REKOR_UUID=108e9186e8c5677a51c33e77fb56b7f99fdf192905340ce9abdc60589cba2da3451c60ad738768c2
Obtains the list of images with sha from the attestation
REKOR_ATTESTATION_IMAGES=$(rekor-cli get --uuid "$REKOR_UUID" --format json | jq -r .Attestation | jq -r '.subject[]|.name + ":v1.11.1@sha256:" + .digest.sha256')
Download the release file

done

Changes

⚠️ Security Fixes

• GHSA-wjxp-xrpv-xpff / CVE-2026-40161 (HIGH): Git resolver API mode leaks system-configured API token to user-controlled serverURL. A user who can create TaskRuns can exfiltrate the system Git API token by pointing the resolver at an attacker-controlled server.

• GHSA-94jr-7pqp-xhcq / CVE-2026-40938 (HIGH): Git resolver unsanitized revision parameter enables argument injection. A malicious revision value can inject arbitrary flags into the git CLI, potentially leading to remote code execution on the resolver pod.

• GHSA-rx35-6rhx-7858 / CVE-2026-40923 (Medium): VolumeMount path restriction bypass via missing filepath normalization. Paths like /tekton/../sensitive bypass the /tekton/ prefix restriction check.

• GHSA-rmx9-2pp3-xhcr / CVE-2026-25542 (Medium): VerificationPolicy regex pattern bypass via substring matching. Unanchored patterns allow partial matches, letting unsigned resources pass verification.

• GHSA-m2cx-gpqf-qf74 / CVE-2026-40924 (Medium): HTTP resolver unbounded response body read enables OOM denial of service. A malicious URL returning a very large response can exhaust the resolver pod's memory. Response body is now limited to 1 MiB.

Tekton Pipeline Releases

Release Frequency

Tekton Pipelines follows the Tekton community [release policy][release-policy] as follows:

• Versions are numbered according to semantic versioning: vX.Y.Z
• A new release is produced on a monthly basis
• Four releases a year are chosen for long term support (LTS). All remaining releases are supported for approximately 1 month (until the next release is produced)
  • LTS releases take place in January, April, July and October every year
  • The first Tekton Pipelines LTS release will be v0.41.0 in October 2022
  • Releases happen towards the middle of the month, between the 13th and the 20th, depending on week-ends and readiness

Tekton Pipelines produces nightly builds, publicly available on gcr.io/tekton-nightly.

Transition Process

Before release v0.41 Tekton Pipelines has worked on the basis of an undocumented support period of four months, which will be maintained for the releases between v0.37 and v0.40.

Release Process

Tekton Pipeline releases are made of YAML manifests and container images. Manifests are published to cloud object-storage as well as [GitHub][tekton-pipeline-releases]. Container images are signed by [Sigstore][sigstore] via [Tekton Chains][tekton-chains]; signatures can be verified through the [public key][chains-public-key] hosted by the Tekton Chains project.
