CVE-2023-48299 is a medium-severity flaw (CVSS 5.3) affecting torchserve. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

TorchServe is a tool for serving and scaling PyTorch models in production. Starting in version 0.1.0 and prior to version 0.9.0, using the model/workflow management API, there is a chance of uploading potentially harmful archives that contain files that are extracted to any location on the filesystem that is within the process permissions. Leveraging this issue could aid third-party actors in hiding harmful code in open-source/public models, whic

pytorch torchserve UPGRADE

Affected: >= 0.1.0 and < 0.9.0

Fixed in: 0.9.0

Safe to downgrade to: a release before 0.1.0

1. Check installed version

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

2. UPGRADE to 0.9.0 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade torchserve

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 0.1.0 (Debian / Ubuntu)

apt-cache madison torchserve sudo apt install torchserve=<VERSION_BEFORE_0.1.0> sudo apt-mark hold torchserve

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

dnf --showduplicates list torchserve sudo dnf downgrade torchserve-<VERSION_BEFORE_0.1.0> sudo dnf versionlock add torchserve

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.
