CVE-2026-88013: rclone is a command-line program to sync files and directories to and from different cloud storage providers

Routine

LOW 3.7REMOTEUPGRADE

CVE-2026-88013 is a low-severity flaw (CVSS 3.7) affecting rclone. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

rclone is a command-line program to sync files and directories to and from different cloud storage providers. From 1.49.0 until 1.75.1, the HTTP backend attaches headers configured through --http-headers or headers= to requests in backend/http/http.go, while its fshttp.NewClient client follows redirects without a backend-specific http.Client.CheckRedirect policy. A configured remote that redirects to another host can therefore cause custom secret

Why this priority

Remotely exploitable, no login, no user action

A fixed release or distro patch exists.

rclone rclone UPGRADE

Affected: >= 1.49.0 and < 1.75.1

Fixed in: 1.75.1

Safe to downgrade to: a release before 1.49.0

1. Check installed version

apt-cache policy rclone || rpm -q rclone || rclone --version

2. UPGRADE to 1.75.1 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade rclone

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade rclone

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 1.49.0 (Debian / Ubuntu)

apt-cache madison rclone sudo apt install rclone=<VERSION_BEFORE_1.49.0> sudo apt-mark hold rclone

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list rclone sudo dnf downgrade rclone-<VERSION_BEFORE_1.49.0> sudo dnf versionlock add rclone

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
