CVE-2026-29090 is a high-severity flaw (CVSS 8.8) affecting rucio. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

### Summary A SQL injection vulnerability exists in Rucio versions 1.30.0 and later before 35.8.5, 38.5.5, 39.4.2, and 40.1.1, in `FilterEngine.create_postgres_query()`. This allows any authenticated Rucio user to execute arbitrary SQL against the PostgreSQL metadata database through the DID search endpoint (`GET /dids/<scope>/dids/search`). When the `postgres_meta` metadata plugin is configured, attacker-controlled filter keys and values are in

cern rucio UPGRADE

Affected: >= 1.30.0 and < 35.8.5 · >= 36.0.0 and < 38.5.5 · >= 39.0.0 and < 39.4.2 · >= 40.0.0 and < 40.1.1

Fixed in: 35.8.5, 38.5.5, 39.4.2, 40.1.1

Safe to downgrade to: a release before 1.30.0

1. Check installed version

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

2. UPGRADE to 35.8.5 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade rucio

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 1.30.0 (Debian / Ubuntu)

apt-cache madison rucio sudo apt install rucio=<VERSION_BEFORE_1.30.0> sudo apt-mark hold rucio

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

dnf --showduplicates list rucio sudo dnf downgrade rucio-<VERSION_BEFORE_1.30.0> sudo dnf versionlock add rucio

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.
