"value": "OpenBao is an open source identity-based secrets management system. Prior to 2.5.5, an authenticated OpenBao caller with write access to transit/keys/* could terminate the server process by setting derived to true while the type parameter selected rsa-, ecdsa-, or ed25519. The Transit policy creation path in builtin/logical/transit/backend.go and sdk/helper/keysutil/policy.go could reach an error path that double-unlocked a mutex while handling this invalid asymmetric derived-key combination, causing a panic, no HTTP response, process exit, and denial of service. JSON and HCL key-creation requests can express the triggering combination. This issue is fixed in version 2.5.5."
