MEDIUM 6.5REMOTEDOWNGRADE

CVE-2026-12482 is a medium-severity flaw (CVSS 6.5) affecting keras. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

A vulnerability in keras-team/keras version 3.12.0 allows an attacker to craft a malicious tar archive that bypasses the `filter_safe_tarinfos` validation in `keras/src/utils/file_utils.py`. Specifically, symlink entries are not subjected to the same `is_path_in_dir` validation as regular file entries, allowing symlinks to be created outside the intended extraction directory. This can lead to symlink-based file read, file overwrite, or directory

keras keras DOWNGRADE

Affected: 3.12.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 3.12.0

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 3.12.0 (Debian / Ubuntu)

apt-cache madison keras sudo apt install keras=<VERSION_BEFORE_3.12.0> sudo apt-mark hold keras

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list keras sudo dnf downgrade keras-<VERSION_BEFORE_3.12.0> sudo dnf versionlock add keras

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.
