CVE-2026-103106 · Severity: high · CVSS 7.8 · Published 2026-09-30

Pexip Infinity is a video conferencing and unified communications platform used by enterprises for meetings and real-time communication. An attacker who gains local access to a Pexip Infinity server can exploit improper input validation in an internal service to escalate their privileges to root, giving them complete control over the system. This would allow them to access sensitive meeting data, intercept communications, or take the system offline.

## Technical details

An internal Pexip Infinity service fails to properly validate input, allowing privilege escalation from local access to root. The vulnerability requires an attacker to first achieve local code execution on a node (via another vulnerability or administrative OS access), then exploit the improper input validation to escalate to root privileges. A patch is available in versions 38.2, 39.2, 40.1, and 41.0 or later.
