Report: CVE-2026-42576 - apko `DiscoverKeys` has a panic on non-rsa jwks key that causes crash during key

CVE ID :CVE-2026-42576 Published : May 9, 2026, 7:26 p.m. | 27 minutes ago Description :apko allows users to build and publish OCI container images built from apk packages. Prior to version 1.2.7, DiscoverKeys in pkg/apk/apk/implementation.go unconditionally type-asserts JWKS keys as *rsa.PublicKey without checking the key type. If a repository JWKS endpoint returns a non-RSA key (e.g. EC), the unchecked assertion panics and crashes apko. This affects any workflow that initializes the APK database and fetches repository keys. This issue has been patched in version 1.2.7.
