Routine

MEDIUM 6.5UPGRADE

CVE-2026-88028 is a medium-severity flaw (CVSS 6.5) affecting laravel mongodb. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Improper neutralization of special elements in data query logic in the polymorphic relation handling of the MongoDB integration for Laravel can cause a caller-supplied relation identifier to be interpreted as a query condition rather than as a literal identifier. An authenticated user who can influence a stored relation identifier may cause an affected application to return a document other than the intended relation target.

mongodb laravel mongodb UPGRADE

Affected: >= 1.2.0 and < 5.11.0

Fixed in: 5.11.0

Safe to downgrade to: a release before 1.2.0

1. Check installed version

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

2. UPGRADE to 5.11.0 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

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 1.2.0 (Debian / Ubuntu)

apt-cache madison laravel-mongodb sudo apt install laravel-mongodb=<VERSION_BEFORE_1.2.0> sudo apt-mark hold laravel-mongodb

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

dnf --showduplicates list laravel-mongodb sudo dnf downgrade laravel-mongodb-<VERSION_BEFORE_1.2.0> sudo dnf versionlock add laravel-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.
