Doc Text:
A flaw was found in Incus. An improper authorization vulnerability allows an authenticated attacker using restricted Transport Layer Security (TLS) client certificates to retrieve storage bucket credentials. By querying the bucket keys endpoints, the attacker can obtain Simple Storage Service (S3) access and secret keys in the default project, potentially allowing unauthorized reading, modification, or deletion of stored data.

Incus 6.0.3 before 6.0.7, 6.6.0 before 7.0.2, and 7.1.0 before 7.5.0 contains an improper authorization vulnerability that allows restricted TLS clients to read storage bucket keys in the default project.
