CVE-2026-103106 is a high-severity flaw (CVSS 7.8) affecting pexip infinity. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Pexip Infinity before 38.2, plus 39.0, 39.1, and 40.0, is affected by improper input validation within an internal Pexip Infinity service that allows an attacker with local access to escalate privileges to root. Exploitation requires an attacker to be able to run arbitrary code on a node by either achieving remote code execution via some other vulnerability or having administrative access to the operating system.

Why this priority

High severity

A fixed release or distro patch exists.

pexip pexip infinity UPGRADE

Affected: < 38.2 · >= 39.0 and <= 39.1 · 40.0

Fixed in: 38.2

Safe to downgrade to: a release before 39.0

1. Check installed version

apt-cache policy pexip-infinity || rpm -q pexip-infinity || pexip-infinity --version

2. UPGRADE to 38.2 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade pexip-infinity

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade pexip-infinity

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 39.0 (Debian / Ubuntu)

apt-cache madison pexip-infinity sudo apt install pexip-infinity=<VERSION_BEFORE_39.0> sudo apt-mark hold pexip-infinity

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

dnf --showduplicates list pexip-infinity sudo dnf downgrade pexip-infinity-<VERSION_BEFORE_39.0> sudo dnf versionlock add pexip-infinity

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.
