CVE-2026-44949: Suse Rancher

High severity, CVSS 7.0. EPSS: 0.4% chance of exploitation in the next 30 days.

A Rancher FleetWorkspace admission path allowed side effects to occur in the Rancher webhook handler for versions 0.7.0 up to 0.7.10, 0.8.0 up to 0.8.7, 0.9.0 up to 0.9.6 and 0.10.0 up to 0.10.7. An unauthenticated attacker with network access to the in-cluster rancher-webhook service could submit a crafted admission payload and cause workspace-related Kubernetes objects to be created with attacker-chosen identity data.

Affected products

• Suse Rancher: from 0.7.0, before 0.7.10 (fixed in 0.7.10); from 0.8.0, before 0.8.7 (fixed in 0.8.7); from 0.9.0, before 0.9.6 (fixed in 0.9.6); from 0.10.0, before 0.10.7 (fixed in 0.10.7)
