Known issues#

This section describes the MSR known issues with available workarounds, along with a list of current product limitations:

(ENGDTR-5013) Cosign signature details not listed in v1 API response#

The signatures array returned by the MSR v1 repositories/tags API does not include entries for Cosign signatures. Only DCT/Notary signatures are listed there. The cosignSigned field still correctly reports whether an image has one or more Cosign signatures, but individual signature details are not enumerated for Cosign.

Workaround

Cosign signing and verification are client-side operations by design. Use the cosign CLI (for example, cosign tree or cosign verify) as the source of truth for inspecting and validating Cosign signatures on an image.

Critical CVEs in MSR 2.10.0 component images#

Security scans of MSR 2.10.0 might report the following critical vulnerabilities in product component images.

Component Vulnerability CVE Installed version Fixed version
dtr-postgres libcrypto3 (OS package) CVE-2026-34182 3.5.6-r0 3.5.7-r0
dtr-postgres libssl3 (OS package) CVE-2026-34182 3.5.6-r0 3.5.7-r0
dtr-* github.com/containerd/containerd (Go module) CVE-2026-53488 v1.7.12 v1.7.33

These findings present low practical risk for typical MSR deployments:

  • The libcrypto3 and libssl3 packages are present in the dtr-postgres image. This image is not exposed to external networks.
  • MSR uses the containerd dependency as a library for image manifest handling. MSR does not run a containerd daemon, so the CRI code path affected by CVE-2026-53488 does not run.

Resolution

Mirantis plans to address these CVEs in a future release.
