Description OSIDB Bzimport 2026-10-22 20:19:33 UTC 
Incus 7.0.1 before 7.0.2 and 7.2.0 before 7.5.0 contains an authorization bypass vulnerability that allows project-restricted clients to copy volumes by omitting source.type. Attackers can send crafted POST requests to the custom volumes endpoint with a chosen source.project to copy and read other projects' volumes, snapshots, and configuration.
