Incus 7.0.0 before 7.0.2 and 7.1.0 before 7.5.0 Path Traversal via Instance Backup Dependent Volumes
Incus 7.0.0 before 7.0.2 and 7.1.0 before 7.5.0 contains a path traversal vulnerability that allows clients able to create instances to write files on the host. The flaw stems from unvalidated dependent custom volume names in instance backup index.yaml files. Attackers can import a crafted instance backup with ../ sequences in dependent volume names to create root-owned directories with controlled content, leading to full host compromise.
