CVE-2026-115371 Details
Description
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. Attackers can query the bucket keys endpoints to obtain S3 access and secret keys, then read, modify or delete objects in those buckets.
An improper authorization vulnerability has been identified in LXC Incus versions 6.0.3 prior to 6.0.7, 6.6.0 prior to 7.0.2, and 7.1.0 prior to 7.5.0. This vulnerability allows restricted TLS clients to access storage bucket keys in the default project. Attackers can exploit this by querying the bucket keys endpoints to obtain S3 access and secret keys, which can then be used to read, modify, or delete objects in the corresponding buckets.
Users are advised not to keep buckets in the default project on servers that issue restricted client certificates. If this is not feasible, it is recommended to rotate the keys of any bucket that a restricted client may have accessed.
