CRITICAL 9.1REMOTEUPGRADE

CVE-2020-10594 is a critical-severity flaw (CVSS 9.1) affecting django-rest-framework-json web tokens. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

An issue was discovered in drf-jwt 1.15.x before 1.15.1. It allows attackers with access to a notionally invalidated token to obtain a new, working token via the refresh endpoint, because the blacklist protection mechanism is incompatible with the token-refresh feature. NOTE: drf-jwt is a fork of jpadilla/django-rest-framework-jwt, which is unmaintained.

styria django-rest-framework-json web tokens UPGRADE

Affected: >= 1.15.0 and < 1.15.1

Fixed in: 1.15.1

Safe to downgrade to: a release before 1.15.0

1. Check installed version

apt-cache policy django-rest-framework-json-web-tokens || rpm -q django-rest-framework-json-web-tokens || django-rest-framework-json-web-tokens --version

2. UPGRADE to 1.15.1 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade django-rest-framework-json-web-tokens

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade django-rest-framework-json-web-tokens

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 1.15.0 (Debian / Ubuntu)

apt-cache madison django-rest-framework-json-web-tokens sudo apt install django-rest-framework-json-web-tokens=<VERSION_BEFORE_1.15.0> sudo apt-mark hold django-rest-framework-json-web-tokens

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

dnf --showduplicates list django-rest-framework-json-web-tokens sudo dnf downgrade django-rest-framework-json-web-tokens-<VERSION_BEFORE_1.15.0> sudo dnf versionlock add django-rest-framework-json-web-tokens

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.
