Routine

HIGH 7.1UPGRADE

CVE-2026-14199 is a high-severity flaw (CVSS 7.1) affecting grafana. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Only self-managed Grafana instances with Auth Proxy authentication and identity caching enabled (sync_ttl greater than zero) are affected. The Auth Proxy cache key concatenated the username and forwarded identity attributes without a delimiter, so distinct identities could collide on one key. An authenticated user who shapes their own attributes to collide with a higher-privileged user's, while that user's cache entry is live, is authenticated as

Affected: < 11.0.0 · >= 12.4.10 and < 13.0.0 · >= 13.0.8 and < 13.1.0 · >= 13.1.5 and < 13.2.0

Fixed in: 11.0.0, 13.0.0, 13.1.0, 13.2.0

Safe to downgrade to: a release before 12.4.10

1. Check installed version

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

2. UPGRADE to 11.0.0 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade grafana

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 12.4.10 (Debian / Ubuntu)

apt-cache madison grafana sudo apt install grafana=<VERSION_BEFORE_12.4.10> sudo apt-mark hold grafana

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

dnf --showduplicates list grafana sudo dnf downgrade grafana-<VERSION_BEFORE_12.4.10> sudo dnf versionlock add grafana

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.
