Infinity: Incorrect Resource Transfer Between Spheres
CVE-2026-103106 is a high-severity incorrect resource transfer between spheres vulnerability in Infinity from Pexip, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists version 38.2.0 as the first without the flaw, so updating Infinity to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.14% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Infinity to 38.2.0 or a later version.
- Update Pexip Infinity to 38.2 or a later version.
- Read the advisory on docs.pexip.com for workarounds and exact fixed builds.

Official description
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.

The underlying weakness: Incorrect Resource Transfer Between Spheres
The product does not properly transfer a resource/behavior to another sphere, or improperly imports a resource/behavior from another sphere, in a manner that provides unintended control over that resource.
