CVE-2026-78574 is a high-severity flaw (CVSS 7.5) affecting hyperdrive. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

The Okta Hyperdrive Integration plugin resolves a required assembly using a registry path within the current user's hive without integrity verification. The referenced path is loaded via Assembly.LoadFrom without signature validation, resulting in an unverified assembly executing within the context of the host process or elevated installer.

Why this priority

High severity

A fixed release or distro patch exists.

okta hyperdrive UPGRADE

Affected: >= 1.2.0 and <= 1.5.1

Fixed in: newer than 1.5.1

Safe to downgrade to: a release before 1.2.0

1. Check installed version

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

2. UPGRADE to newer than 1.5.1 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade hyperdrive

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 1.2.0 (Debian / Ubuntu)

apt-cache madison hyperdrive sudo apt install hyperdrive=<VERSION_BEFORE_1.2.0> sudo apt-mark hold hyperdrive

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

dnf --showduplicates list hyperdrive sudo dnf downgrade hyperdrive-<VERSION_BEFORE_1.2.0> sudo dnf versionlock add hyperdrive

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.
