SUSE CVE-2026-55588

ORAS OCI Registry As Storage is a CLI and library for managing artifacts in OCI registries. In ORAS CLI versions up to and including 1.3.2, the recursive referrer traversal does not track visited descriptors, so a malicious OCI registry that returns a cyclic referrer graph causes unbounded...

GHSA-298F-872V-2RCX ORAS CLI: Cyclic Referrer Graph Can Cause Unbounded Recursion and Resource Consumption

Summary A malicious OCI registry can return a cyclic referrer graph e.g. A - A or A - B - A. The ORAS CLI's recursive referrer traversal does not track visited descriptors, so a cycle causes unbounded recursion and memory growth — a client-side denial of service. This affects oras discover...

GHSA-MF7Q-R4RV-JV94 Crossplane's TOCTOU between cosign verification and image fetch in xpkg.CachedClient allows tag-based package install to bypass signature check

Summary Crossplane allows package signature verification to be configured via the ImageConfig mechanism. When enabled, the package manager uses cosign to verify that packages are correctly signed before pulling and installing them. When a package is installed using a tag reference e.g., a semanti...
