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...

Time-of-check Time-of-use (TOCTOU) Race Condition

Overview Affected versions of this package are vulnerable to Time-of-check Time-of-use TOCTOU Race Condition via the CachedClient.Get flow in pkg/xpkg/client.go. An attacker controlling an OCI registry can serve one signed image to fetcher.Head and validator.Validate, then swap the tag to differe...

CVE-2026-55588

A flaw was found in ORAS OCI Registry As Storage CLI. A remote attacker, by operating a malicious OCI Open Container Initiative registry that returns a cyclic referrer graph, could cause unbounded recursion and memory growth in the client. This vulnerability leads to a client-side Denial of Servi...
