CVE-2026-115356

5.3 medium SSVC exploitation: none Deferred
NVD · CVE.org

OpenBao before 2.6.4 and 2.7.x before 2.7.1 does not verify, when renewing a token issued by the Kubernetes Auth method, that the service account token originally used to authenticate is still valid. An authenticated attacker can keep renewing such tokens to persist access after the Kubernetes service account has been deleted.

Fix

Nothing published yet: no patch, vendor advisory or mitigation reference on NVD, no vendor advisory in the News for this CVE, not in CISA's KEV, no fixed package version. BaselineWatch does not guess at one.
