Modified

Severity

7.1 (High) CVSS_V4 - CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N CVSS Calculator

Summary

OpenBao's cross-namespace lease revocation via legacy sys/revoke path bypasses ACL

Details

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.
