No Socket, No Privs, No Problem: Weaponizing OCI Registries for SSRF, Credential Theft, and Container Escapes

David Rochester and Nicholas Gould · DEF CON

AI-collected research leads through 3 November 2026, including a November–October–September missed-article review and a targeted multilingual search alongside earlier community-source sweeps. Unranked, incomplete, not community-vetted, and subject to change.

Examines malicious OCI registry challenges and blob redirects as privileged fetch operations. Reusing a digest for a layer and configuration changes verification state and retains SSRF response bytes for exfiltration; a separate model-import path reaches an unsandboxed macOS host service from a container-accessible API.
