Doc Text:
A flaw was found in OpenBao. When the initial deletion of a namespace fails, subsequent attempts to remove it do not fully clear all associated data before the namespace is marked as deleted. This can result in residual data, such as outstanding leases and unrelated storage entries, not being properly removed from the system.

Description OSIDB Bzimport 2026-05-14 16:02:40 UTC
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.
