rclone: WebDAV Credentials Survive a Same-Host HTTPS-to-HTTP Redirect

Summary WebDAV's default redirect handling can replay Basic authorization and configured Cookie headers over plaintext HTTP after a same-host HTTPS-to-HTTP redirect. This was reproduced through the real backend. Unlike the low-impact STS token in rclone's published S3 redirect advisory, Basic...

CVE-2026-71311

rclone (pre-1.75.0) is affected by a CRLF injection in FTP filename handling: a valid but nondefault encoding in backend/ftp/ftp.go can restore raw CR/LF before an attacker-controlled path is interpolated into the FTP control channel. github.com/jlaffaye/ftp formats the argument via textproto.Con...

rclone: Path traversal in serve s3 allows reading and overwriting root-level files

Summary rclone serve s3 allows a client to read and write files at the root of the remote which would normally be inaccessible by using dot-dot path segments in the object key. It does not allow reading files outside of the root. A request such as GET /bucket/../root-secret.txt is handled as an...

rclone: Unbounded HTTP CONNECT Response Headers Can Exhaust rclone Memory

Summary The shared HTTP CONNECT helper parses a proxy response with http.ReadResponse over an unrestricted buffered reader. The production helper accepted a valid response containing a 2 MiB header in three consecutive runs. A malicious or compromised configured proxy, or an active on-path actor...

CVE-2026-71310

The CVE affects the rclone project before version 1.75.0, where the shared HTTP CONNECT helper in lib/proxy/http.go incorrectly parses proxy CONNECT responses using http.ReadResponse over an unrestricted reader. This unbounded parsing enables a malicious or on-path proxy to send oversized headers...

CVE-2026-71310 rclone: Unbounded HTTP CONNECT Response Headers Can Exhaust rclone Memory

rclone is a command-line program to sync files and directories to and from different cloud storage providers. Prior to 1.75.0, the shared HTTP CONNECT helper in lib/proxy/http.go parses proxy CONNECT responses with http.ReadResponse over an unrestricted buffered reader, allowing a malicious or...

rclone: Unvalidated symlink target in local `--links` — arbitrary file write from an untrusted remote

Summary With -l/--links, rclone serializes symlinks as .rclonelink text objects whose body is the link target. When rclone writes such an object to a local destination, it recreates the symlink with os.Symlink, and performs NO validation of the target. If the source is attacker-controlled, the...

rclone: Incomplete path validation allows backend root escape in serve restic

Summary rclone serve restic does not correctly reject URL paths beginning with ../. On affected backends, an attacker who can access the REST endpoint can read, create, overwrite, or delete objects outside the path configured by the operator. The issue affects rclone v1.40 through rclone v1.74.4...

CVE-2026-71309 rclone: Incomplete path validation allows backend root escape in serve restic

rclone is a command-line program to sync files and directories to and from different cloud storage providers. From 1.40.0 until 1.75.0, rclone serve restic does not correctly reject URL paths beginning with ../ in cmd/serve/restic/restic.go WithRemote, which accepts a leading parent path and pass...

CVE-2026-71309

CVE-2026-71309 affects rclone up to v1.75.0 where the serve restic WithRemote path validation in cmd/serve/restic/restic.go fails to reject leading "../" paths. This allows an attacker with REST access to influence GET/HEAD/POST/DELETE operations against configured backends (WebDAV, FTP, HTTP, Me...
