CVE-2026-41704— Cloud Foundry BOSH Director 安全漏洞

Compromised VM can make arbitrary blobstore deletes

AgentClient#handle_method (lines 264-303) processes every NATS reply. It calls inject_compile_log (line 273) on every response, which reads response['value']['result']['compile_log_id'] (line 332-338) and passes it to download_and_delete_blob. Separately, any response containing 'exception' goes through format_exception (lines 308-325), which reads exception['blobstore_id'] and also calls download_and_delete_blob. That helper (lines 344-349) calls ResourceManager#get_resource(blob_id) and, in an ensure block, ResourceManager#delete_resource(blob_id). ResourceManager (resource_manager.rb:62-70) calls blobstore.delete(id) on the single shared Director blobstore with no UUID-format check, no ownership check, and no namespace prefix. Affected versions: BOSH Director: All versions prior to v282.1.12

访问控制不恰当

Cloud Foundry BOSH Director 安全漏洞

Cloud Foundry BOSH Director是美国Cloud Foundry公司的一个云基础设施部署与生命周期管理平台。 Cloud Foundry BOSH Director v282.1.12之前版本存在安全漏洞，该漏洞源于AgentClient在处理NATS回复时未对blob_id进行UUID格式检查、所有权检查和命名空间前缀检查，直接传递给blobstore操作，可能导致未授权访问。
