CVE-2026-115357 Details
Description
OpenBao before 2.6.4 and 2.7.x before 2.7.1 fails to write response audit entries for the unauthenticated sys/generate-root, sys/rekey, and sys/rekey-recovery-key endpoints when request audit logging succeeds but response audit logging fails. An attacker using these endpoints can complete root token generation or rekey operations without a corresponding response audit record, hindering forensic detection.
A vulnerability exists in OpenBao versions prior to 2.6.4 and 2.7.0 prior to 2.7.1, where the application fails to properly log response audits for certain unauthenticated endpoints. Specifically, the sys/generate-root, sys/rekey, and sys/rekey-recovery-key endpoints do not generate response audit entries when request logging is successful but response logging fails. This oversight allows an attacker to complete root token generation or rekey operations without leaving a response audit trail, which could impede forensic investigations.
Users can upgrade to OpenBao version 2.7.1 or 2.6.4, where this vulnerability has been patched. If using OpenBao 2.5.3 or higher, ensure that the 'disable_unauthed_rekey_endpoints' and 'disable_unauthed_generate_root_endpoints' settings are enabled, which is the default configuration.
