CVE-2026-93537: A user who can supply bundle content to a repository referenced by a GitRepo resource, for example through Git

Routine

MEDIUM 6.5UPGRADE

CVE-2026-93537 is a medium-severity flaw (CVSS 6.5) affecting rancher fleet. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

A user who can supply bundle content to a repository referenced by a GitRepo resource, for example through Git push access, or through permission to create or modify a GitRepo, can cause SUSE Rancher Fleet to read files from the filesystem of the environment that processes the bundle and include their contents in the generated Bundle resource. This can expose configuration or credential material that the user has no Kubernetes RBAC permission to

Why this priority

No elevated risk signals yet

A fixed release or distro patch exists.

Safe to downgrade to: a release before 0.12.0

1. Check installed version

apt-cache policy rancher-fleet || rpm -q rancher-fleet || rancher-fleet --version

2. UPGRADE to 0.12.20 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade rancher-fleet

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade rancher-fleet

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 0.12.0 (Debian / Ubuntu)

apt-cache madison rancher-fleet sudo apt install rancher-fleet=<VERSION_BEFORE_0.12.0> sudo apt-mark hold rancher-fleet

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

dnf --showduplicates list rancher-fleet sudo dnf downgrade rancher-fleet-<VERSION_BEFORE_0.12.0> sudo dnf versionlock add rancher-fleet

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.
