CVE-2025-59824Network attack vector

Network pivoting via unchecked packet destinations

Published Sep 24, 2025 · Updated Sep 24, 2025

Incorrect authorization in Sidero Labs Omni before 0.48.0 allows attackers controlling a Talos workload to send arbitrary SideroLink packets. The Omni WireGuard interface checks each packet's source against its assigned peer IPv6 address but accepts any destination address. A host-networked workload can reach the link; disabled forwarding exposes Omni or host services, while enabled forwarding permits access to connected systems or deeper network routes.
