BOSH Director vulnerabilities

CVE-2026-41704 affects BOSH Director, where the AgentClient#handle_method processes NATS replies, leading to unauthorized access to resources in the blobstore. The lack of proper checks, such as UUID format validation, ownership verification, and namespace prefix checks, allows unauthorized deletion of resources.

CVE-2026-41009 affects BOSH Director, where the agent's response to long-running requests may lead to unauthorized access to system files. Due to the lack of normalization of the blob identifier, it is possible to reference files outside the blobstore root.

In BOSH Director (all versions prior to v282.1.12), the ReleaseJob#unpack function builds job_dir and job_tgz paths using a name from the attacker-supplied release.MF file. These paths are interpolated into a shell command without proper escaping, allowing shell command injection via metacharacters in the name. An attacker can execute arbitrary commands in the context of BOSH Director.
