CVE-2026-33213: Redash is a package for data visualization and sharing

Routine

MEDIUM 6.1UPGRADE

CVE-2026-33213 is a medium-severity flaw (CVSS 6.1) affecting redash. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Redash is a package for data visualization and sharing. From 5.0.2 to 26.3.0, the get_next_path() function in Redash's authentication module stripped the scheme and netloc from user-supplied next parameters but did not normalize multiple leading slashes, allowing a crafted login URL such as /login?next=////evil.com to redirect users to an external attacker-controlled site after authentication.

Why this priority

No elevated risk signals yet

A fixed release or distro patch exists.

redash redash UPGRADE

Affected: >= 5.0.2 and < 26.03.1

Fixed in: 26.03.1

Safe to downgrade to: a release before 5.0.2

1. Check installed version

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

2. UPGRADE to 26.03.1 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade redash

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 5.0.2 (Debian / Ubuntu)

apt-cache madison redash sudo apt install redash=<VERSION_BEFORE_5.0.2> sudo apt-mark hold redash

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

dnf --showduplicates list redash sudo dnf downgrade redash-<VERSION_BEFORE_5.0.2> sudo dnf versionlock add redash

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.
