CVE-2026-55188

RustFS’s ListRemoteTargetHandler in versions 1.0.0-alpha.1 through 1.0.0-beta.8 contains an authorization bypass that only checks for credentials and neglects to verify replication or admin permissions. This allows an authenticated user without bucket/admin rights to list remote replication targe...

CVE-2026-49991

RustFS 1.0.0-beta.4 is affected by a path traversal vulnerability in the Snowball auto-extract feature. Authenticated users with only PutObject permission on their own bucket can write arbitrary objects into other users’ buckets, breaking multi-tenant isolation. Root causes include: (1) No ../ sa...

CVE-2026-55189

RustFS (distributed object storage in Rust) contains a vulnerability from 1.0.0-alpha.1 through 1.0.0-beta.9 where enabling the FTP frontend lets FTP read and probe handlers bypass the IAM authorization function, allowing authenticated users to read objects and probe buckets regardless of IAM pol...

CVE-2026-55189 RustFS: FTP frontend skips IAM authorization on object reads

RustFS is a distributed object storage system built in Rust. From 1.0.0-alpha.1 until 1.0.0-beta.9, when the FTP frontend is enabled, the FTP read and probe handlers dispatch directly to the storage backend without ever calling the IAM authorization function that the FTP write/list handlers and t...

CVE-2026-55838 RustFS: Missing admin authorization on /rustfs/admin/v3/metrics allows any authenticated user to read server metrics

RustFS is a distributed object storage system built in Rust. In 1.0.0-beta.7 and earlier, the real-time metrics endpoint at /rustfs/admin/v3/metrics is accessible to any valid IAM user regardless of their assigned policy. Every other admin handler in the codebase calls validateadminrequest to...

CVE-2026-55838

CVE-2026-55838 (RustFS) : In versions up to 1.0.0-beta.7, the real-time metrics endpoint /rustfs/admin/v3/metrics is accessible to any valid IAM user, because MetricsHandler skips the admin-request validation that other admin handlers perform. As a result, a user whose policy allows only their ow...
