HIGH 7.5REMOTEUPGRADE

CVE-2026-50193 is a high-severity flaw (CVSS 7.5) affecting jackson-databind. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.13.0 until 2.14.0, a potential Denial-of-Service exists when attacker sends deeply nested JSON if (and only if) the service reads deeply nested (1000s of levels) JSON as JsonNode (ObjectMapper.readTree()) and writes out same (or modifided) node using JsonNode.toString(). This can consume significant amount of resources with c

fasterxml jackson-databind UPGRADE

Affected: >= 2.10.0 and < 2.14.0

Fixed in: 2.14.0

Safe to downgrade to: a release before 2.10.0

1. Check installed version

apt-cache policy jackson-databind || rpm -q jackson-databind || jackson-databind --version

2. UPGRADE to 2.14.0 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade jackson-databind

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade jackson-databind

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 2.10.0 (Debian / Ubuntu)

apt-cache madison jackson-databind sudo apt install jackson-databind=<VERSION_BEFORE_2.10.0> sudo apt-mark hold jackson-databind

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

dnf --showduplicates list jackson-databind sudo dnf downgrade jackson-databind-<VERSION_BEFORE_2.10.0> sudo dnf versionlock add jackson-databind

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.
