MEDIUM 5.9REMOTEUPGRADE

CVE-2026-54698 is a medium-severity flaw (CVSS 5.9) affecting graphql engine. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Hasura is an open-source product that provides users GraphQL or REST APIs. Prior to 2.49.2 and 2.45.5, a user can use a where clause on a table computed field (returning SETOF some_table) to infer row values that ought to be filtered for their role based on some_table's row-level permissions. While such rows cannot be returned directly, like predicates on strings for instance allow values to be brute forced efficiently with the where clause as an

hasura graphql engine UPGRADE

Affected: >= 2.45.0 and <= 2.45.5 · >= 2.46.0 and <= 2.49.2

Fixed in: newer than 2.49.2

Safe to downgrade to: a release before 2.45.0

1. Check installed version

apt-cache policy graphql-engine || rpm -q graphql-engine || graphql-engine --version

2. UPGRADE to newer than 2.49.2 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade graphql-engine

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade graphql-engine

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 2.45.0 (Debian / Ubuntu)

apt-cache madison graphql-engine sudo apt install graphql-engine=<VERSION_BEFORE_2.45.0> sudo apt-mark hold graphql-engine

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

dnf --showduplicates list graphql-engine sudo dnf downgrade graphql-engine-<VERSION_BEFORE_2.45.0> sudo dnf versionlock add graphql-engine

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.
