CVE-2026-72920
CriticalCVSS 9.8Summary
SeaweedFS before 4.24 registers the SeaweedIdentityAccessManagement gRPC service without mandatory authentication when jwt.filer_signing.key is unset. Any client with gRPC access can create users and access keys, gaining S3 administrative control.
Risk Assessment
An unauthenticated attacker can gain full control over S3, creating credentials and managing policies, leading to data compromise.
Recommendation
Upgrade SeaweedFS to version 4.24 or later. Set jwt.filer_signing.key and restrict access to the filer's gRPC port.
Original NVD description (English source)
SeaweedFS is a distributed storage system. Prior to 4.24, the filer registers the SeaweedIdentityAccessManagement gRPC service without mandatory authentication when jwt.filer_signing.key is unset, allowing any client that can reach the filer gRPC port to invoke CreateUser, CreateAccessKey, PutPolicy, and related IAM RPCs to mint credentials and gain S3 administrative control. This issue is fixed in versions 4.24.
