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

RELEASE_FILE=https://infra.tekton.dev/tekton-releases/pipeline/previous/v1.6.1/release.yaml
REKOR_UUID=108e9186e8c5677a4ba876bd39916b4123385435497b76a0e5cfee59ac292230166e5ded5b9d4596

REKOR_ATTESTATION_IMAGES=$(rekor-cli get --uuid "$REKOR_UUID" --format json | jq -r .Attestation | jq -r '.subject[]|.name + ":v1.6.1@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.
