Summary
OpenBao is an open source identity-based secrets management system. Prior to 2.5.3, when OpenBao's initial namespace deletion fails, subsequent retries fail to properly remove all data before marking the namespace as deleted. This can affect any outstanding leases as well as potentially leaving unrelated storage entries around. This vulnerability is fixed in 2.5.3.
