CVE-2026-45808
OpenBao's cross-namespace lease revocation via legacy sys/revoke path bypasses ACL
發布日:2026/5/28修改日:2026/5/28
描述
# Impact OpenBao's namespaces provide multi-tenant separation. A tenant who intentionally leaks lease identifiers can have their lease and underlying credential revoked or renewed by a user in another tenant via the legacy, undocumented `sys/revoke` and `sys/renew` endpoints. # Patch This will be addressed in v2.5.4.
