What is CVE-2026-115370?

A restriction bypass vulnerability in Incus versions 6.0.5 prior to 6.0.7, 6.12.0 prior to 7.0.2, and 7.1.0 prior to 7.5.0 enables unauthorized users with instance creation rights to execute a pull mode migration through clustered refresh requests. This could allow malicious actors to send refresh migration requests for existing instances, compelling the server to initiate outbound TLS websocket connections which can lead to unauthorized probing of reachable services and potential data exposure.

Affected Version(s)

incus 6.0.5 < 6.0.7

incus 6.12.0 < 7.0.2

incus 7.1.0 < 7.5.0
