CVE-2025-64761 | OpenBao Privileged Operator Identity Group Root Escalation

OpenBao is an open source identity-based secrets management system. Prior to version 2.4.4, a privileged operator could use the identity group subsystem to add a root policy to a group identity group, escalating their or another user's permissions in the system. Specifically this is an issue when: an operator in the root namespace has access to identity/groups endpoints and an operator does not have policy access. Otherwise, an operator with policy access could create or modify an existing policy to grant root-equivalent permissions through the sudo capability. This issue has been patched in version 2.4.4.

Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:H)
They need powerful rights—admin, root, or similar—before this pays off.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
