Affected: Bitnami: cosign

Cosign provides code signing and transparency for containers and binaries. Prior to 3.0.6 and 2.6.3, cosign verify-blob-attestation may erroneously report a "Verified OK" result for attestations with malformed payloads or mismatched predicate types. For old-format bundles and detached signatures, this was due to a logic flaw in the error handling of the predicate type validation. For new-format bundles, the predicate type validation was bypassed completely. This vulnerability is fixed in 3.0.6 and 2.6.3.

 https://cve.radiocsirt.org/vuln/ghsa-w6c6-c85g-mmv6 GHSA-w6c6-c85g-mmv6 — Cosign's verify-blob-attestation reports false positive when payload parsing fails 2026-10-04T08:32:02.756697+00:00

Affected: Go: github.com/sigstore/cosign

## Description

`cosign verify-blob-attestation` may erroneously report a "Verified OK" result for attestations with malformed payloads or mismatched predicate types. For old-format bundles and detached signatures, this was due to a logic flaw in the error handling of the predicate type validation. For new-format bundles, the predicate type validation was bypassed completely.

## Impact

When `cosign verify-blob-attestation` is used without `--check-claims` set to `true`, an attestation that has a valid signature but a malformed or unparsable payload would be incorrectly validated. Additionally, systems relying on `--type <predicate type>` to reject attestations with mismatched types would be lead to trust the unexpected attestation type.

## Patches

v3.0.6, v2.6.3

## Workarounds

Always set `--check-claims=true` for attestation verification.
