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 recursion and memory growth. This affects oras discover, whose recursive traversal is enabled by default because the --depth option defaults to 0 (unlimited), as well as the recursive referrer counting used by the oras backup and oras restore workflows. A cyclic graph can be as simple as A referring to B and B referring back to A. A malicious registry can use this to cause a client-side denial of service, exhausting CPU and memory and hanging automation or CI/CD pipelines that run ORAS against untrusted registry metadata. The vulnerability does not extend to code execution, artifact substitution, or integrity bypass. This issue has been fixed in version 1.3.3.
