- Summary
- OpenBao: Cross-namespace lease revocation/renewal via canonical sys/leases/{revoke,renew} — incomplete fix of CVE-2026-45808
- Details
-
Summary
OpenBao users with access to the
sys/leases/revoke/:lease_idendpoint in any namespace can revoke leases in any other namespace as long as the lease identifier is known to them, bypassing ACLs that should apply for cross-namespace revocations.Impact
OpenBao's namespaces provide multi-tenant separation. A tenant who intentionally leaks lease identifiers can have their lease and underlying credential revoked by a user in another tenant.
Patch
This will be fixed in OpenBao v2.5.5.
