CRITICAL 9.8REMOTEUPGRADE

CVE-2026-41179 is a critical-severity flaw (CVSS 9.8) 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. Starting in version 1.48.0 and prior to version 1.73.5, the RC endpoint `operations/fsinfo` is exposed without `AuthRequired: true` and accepts attacker-controlled `fs` input. Because `rc.GetFs(...)` supports inline backend definitions, an unauthenticated attacker can instantiate an attacker-controlled backend on demand. For the WebDAV ba

rclone rclone UPGRADE

Affected: >= 1.48.0 and < 1.73.5

Fixed in: 1.73.5

Safe to downgrade to: a release before 1.48.0

1. Check installed version

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

2. UPGRADE to 1.73.5 (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 1.48.0 (Debian / Ubuntu)

apt-cache madison rclone sudo apt install rclone=<VERSION_BEFORE_1.48.0> 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_1.48.0> 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.
