Obtain the attestation:

REKOR_UUID=108e9186e8c5677a876fa60f37e6445548fabd0dc463c51c7f8b06b07c242eb0921ee277008b088c
rekor-cli get --uuid $REKOR_UUID --format json | jq -r .Attestation | jq .

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

RELEASE_FILE=https://infra.tekton.dev/tekton-releases/pipeline/previous/v1.3.3/release.yaml
REKOR_UUID=108e9186e8c5677a876fa60f37e6445548fabd0dc463c51c7f8b06b07c242eb0921ee277008b088c

# 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 + ":v1.3.3@sha256:" + .digest.sha256')

# Download the release file
curl -L "$RELEASE_FILE" > release.yaml

# For each image in the attestation, match it to the release file
for image in $REKOR_ATTESTATION_IMAGES; do
  printf $image; grep -q $image release.yaml && echo " ===> ok" || echo " ===> no match";
done

Changes

⚠️ Security Fixes

GHSA-j5q5-j9gm-2w5c (Critical): Path traversal in git resolver allows reading arbitrary files from the resolver pod. Fixed by validating the pathInRepo parameter to prevent directory traversal.
GHSA-cv4x-93xx-wgfj / CVE-2026-33022 (Medium): Controller panic via long resolver name in TaskRun/PipelineRun. A user with permission to create TaskRuns or PipelineRuns could crash the controller into a restart loop by setting a resolver name of 31+ characters, causing denial of service cluster-wide. Thanks to @1seal for reporting this vulnerability.

Features

✨ Add support for hostUsers field in PodTemplate to control user namespace isolation (#9323)

Fixes

🐛 fix: panic in v1beta1 matrix validation for invalid result refs (#9260) — Resolved an issue where Pipelines with invalid result references in matrix parameters would cause a panic during validation (v1beta1 API)
🐛 fix(pipelinerun): fix the issue of massive invalid status updates caused by unordered arrays, which will greatly impact the resource load and stability of the apiserver (#9312)
🐛 fix(#8940): Fix token-authentication header in git resolver (#9115) — Before this change, there was a regression in which the git resolver was not authenticating with the provided gitToken and gitTokenKey, breaking the git resolver's http token-based auth. After this change, all git operations performed by the git resolver use the provided gitToken for remote authentication.
🐛 fix: Prevent excessive reconciliation when timeout disabled (#9355)

Misc

🔨 ci: add CI summary fan-in job for branch protection (#9409)
🔨 tekton: update plumbing ref to latest commit (#9414)
🔨 tekton: update plumbing ref to include full image references fix (#9403)
🔨 Backported test reliability fixes including reduced test parallelism, image migration from DockerHub to mirror.gcr.io, and improved dind-sidecar probe configuration (#9250)
