Release Notes

sigstore/cosign

v1.12.1

Compare Source

Highlights

• Pulls Fulcio root and intermediate when --certificate-chain is not passed into verify-blob. The v1.12.0 release introduced a regression: when COSIGN_EXPERIMENTAL was not set, cosign verify-blob would check a --certificate (without a --certificate-chain provided) against the operating system root CA bundle. In this release, Cosign checks the certificate against Fulcio's CA root instead (restoring the earlier behavior).

Bug Fixes

• fix: fixing breaking changes in rekor v1.12.0 upgrade (https://github.com/sigstore/cosign/pull/2260)
• Fixed bug where intermediate certificates were not automatically read from the OCI chain annotation (https://github.com/sigstore/cosign/pull/2244)
• fix: add COSIGN_EXPERIMENTAL=1 for verify-blob (https://github.com/sigstore/cosign/pull/2254)
• fix: fix cert chain validation for verify-blob in non-experimental mode (https://github.com/sigstore/cosign/pull/2256)
• fix: fix secret test, non-experimental bundle should pass (https://github.com/sigstore/cosign/pull/2249)
• Fix e2e test failure, add test for local bundle without rekor bundle (https://github.com/sigstore/cosign/pull/2248)
