Preliminary research

A Realistic Code Execution Exploit Chain in OpenBao and Vault

Alex Scheel · ControlPlane · 28 September 2026

AI-collected research leads through 6 October 2026, including bounded month-by-month reviews of selected social and community sources from January through September. Unranked, incomplete, not community-vetted, and subject to change.

Four OpenBao and Vault flaws are chained from ACME URI-SAN impersonation through non-canonical ACL handling and cross-namespace policy access to Raft snapshot-restore code execution. The writeup explains deployment prerequisites, component root causes and mitigations while withholding the full exploit.
