Routine

MEDIUM 5.3UPGRADE

CVE-2026-13057 is a medium-severity flaw (CVSS 5.3) affecting mongodb. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

An issue in the server’s Atlas Search integration allows an authenticated user to bypass per-user access controls. In sharded topologies, the $search and $searchMeta aggregation stages use internal routing that is normally populated only by the trusted router during sharded search planning. Due to insufficient input validation, an authenticated client can supply these fields directly.

Why this priority

No elevated risk signals yet

A fixed release or distro patch exists.

mongodb mongodb UPGRADE

Affected: >= 8.0.0 and < 8.0.28 · >= 8.2.0 and < 8.2.12 · >= 8.3.0 and < 8.3.7

Fixed in: 8.0.28, 8.2.12, 8.3.7

Safe to downgrade to: a release before 8.0.0

1. Check installed version

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

2. UPGRADE to 8.0.28 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade mongodb

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 8.0.0 (Debian / Ubuntu)

apt-cache madison mongodb sudo apt install mongodb=<VERSION_BEFORE_8.0.0> sudo apt-mark hold mongodb

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

dnf --showduplicates list mongodb sudo dnf downgrade mongodb-<VERSION_BEFORE_8.0.0> sudo dnf versionlock add mongodb

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.
