CVE-2026-45808

Published Aug 7, 2026 CWE-863 EPSS 0.31% (23th pctl)

Overview

CVE-2026-45808 is a known-severity vulnerability. It was published on August 7, 2026.

Technical Description

OpenBao is an open source identity-based secrets management system. Prior to version 2.5.4, 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. This is fixed in OpenBao v2.5.4.
