What an attacker can do
An unauthenticated attacker can submit a multipart body containing many minimal file parts and exhaust the process file-descriptor table within the request-body size limit, causing os.CreateTemp failures, MULTIPART_STRICT_ERROR responses, blocked legitimate uploads, and process-wide inability to open files or sockets. Vendor/CNA’s CVSS 3.1 assessment (base score 5.3/10) rates confidentiality and integrity impact as none; availability impact as low.
