Affected packages
• Go github.com/openbao/openbao: < 0.0.0-20260420173541-6d2e0506e2b4 → fixed in 0.0.0-20260420173541-6d2e0506e2b4
Description
Impact
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.
Patches
This will be patched in OpenBao v2.5.3.
Workarounds
Users may manually remove mounts prior to deleting the namespace.
Audit logs may be used to identify repeated deletion attempts against the same namespace; `sys/raw` can be used to see what leases were not correctly deleted.
