Description

This security bulletin contains information about 1 security vulnerability.


1) Insufficient verification of data authenticity (CVE-ID: CVE-2026-22703)

The vulnerability allows a local user to cause acceptance of an invalid signing bundle.

The vulnerability exists due to insufficient verification of data authenticity in Rekor entry verification when verifying a crafted Cosign bundle. A local user can include an arbitrary valid Rekor entry in the bundle to cause acceptance of an invalid signing bundle.

This only affects verification when a trusted root is provided via --trusted-root or fetched automatically from a TUF repository and no trusted key material is provided via SIGSTORE_REKOR_PUBLIC_KEY.
