Incorrect Authorization

Overview Affected versions of this package are vulnerable to Incorrect Authorization in the handling of per-server authentication proxy options in FTP and S3 remote control servers. An attacker can gain unauthorized access to read, create, overwrite, and delete files by connecting to the affected...

rclone: RC per-server auth-proxy bypass

Summary serve/start accepts protocol options in a per-server proxyOpt object. The FTP and S3 RC adapters parse that object and pass it to their server constructors, but the constructors decide whether proxy authentication is enabled by checking the process-global proxy.Opt.AuthProxy instead of th...

GHSA-C476-6W5Q-JW77 rclone: FTP cross-session auth-proxy backend confusion

Summary The FTP auth-proxy driver stores one obscured password per username in a server-wide map. It does not bind the credential or returned VFS to the authenticated FTP session. If two accepted credentials use the same username but resolve to different proxy backends, the later login overwrites...

rclone: source object names can escape the configured root on upload

Summary Multiple backends, when given a specially crafted object to copy, can escape the backend confinement. | Backend | Keep/Close | Per-backend severity | |---|---|---| | sftp | Medium | Real filesystem escape, fires under default encoding. | | smb | Low-Medium | Escapes to a different SMB sha...

rclone: S3 multipart declared-length memory exhaustion

Summary In streamed multipart mode, serve s3 passes the request's declared part length to multipart.NewRW.ReservecontentLength before reading any part data. Reserve immediately obtains enough 1 MiB pool pages for the entire declared length. The request handler therefore allocates attacker-selecte...

Memory Allocation with Excessive Size Value

Overview Affected versions of this package are vulnerable to Memory Allocation with Excessive Size Value in the Reserve process. An attacker can exhaust system memory and cause service disruption by sending a multipart upload request with a large declared part size in the request headers, without...

GHSA-2P48-J3QC-RX9F rclone: S3 multipart declared-length memory exhaustion

Summary In streamed multipart mode, serve s3 passes the request's declared part length to multipart.NewRW.ReservecontentLength before reading any part data.

CVE-2026-88015

A flaw was found in rclone. When rclone is configured with backend/local and links=true, it exposes symlink targets as .rclonelink objects. A remote attacker can send a crafted Range request with an unchecked positive Range start, leading to a deterministic slice-bounds panic. This issue results ...

DEBIAN-CVE-2026-88045

rclone is a command-line program to sync files and directories to and from different cloud storage providers. From 1.75.0 until 1.75.1, the serve S3 streamed multipart path in cmd/serve/s3/multipart.go passes attacker-controlled contentLength to multipart.NewRW.Reserve before reading request-body...
