Details

As written in the advisory (Markdown source, shown as plain text).

### Impact Accounts with access to the highly-privileged identity entity system in the root namespace may increase their scope directly to the `root` policy. While the identity system always allowed adding arbitrary policies, which in turn could contain capability grants on arbitrary paths, the `root` policy is restricted to manual generation using unseal or recovery key shares. The global `root` policy is not accessible from child namespaces. ### Patches OpenBao v2.3.2 will patch this issue. ### Workarounds Use of `denied_parameters` in any policy which has access to the affected identity endpoints (on [identity entities](https://openbao.org/api-docs/secret/identity/entity/)) may be sufficient to prohibit this type of attack. ### References This issue was disclosed to HashiCorp and is the OpenBao equivalent of the following tickets: - https://discuss.hashicorp.com/t/hcsec-2025-13-vault-root-namespace-operator-may-elevate-token-privileges/76032 - https://nvd.nist.gov/vuln/detail/cve-2025-5999
