Name of the Vulnerable Software and Affected Versions BOSH Director versions prior to 282.1.12

Description The AgentClient#handle method processes NATS replies and invokes inject compile log for every response, which reads the compile log id from response['value']['result']['compile log id'] and passes it to download and delete blob. Additionally, responses containing an exception are processed by format exception, which reads blobstore id from exception['blobstore id'] and also calls download and delete blob. The download and delete blob helper calls ResourceManager#get resource(blob id) and subsequently ResourceManager#delete resource(blob id) within an ensure block. The ResourceManager then calls blobstore.delete(id) on the shared Director blobstore without performing UUID-format checks, ownership verification, or applying a namespace prefix.

Recommendations Update to version 282.1.12 or later.
