Technical details
The vulnerability exists in the nexent backend service (v1.7.5.2) due to a lack of security controls on the 'DELETE /storage/{object_name:path}' API endpoint. This endpoint fails to implement authentication, authorization, or proper input validation. A remote, unauthenticated attacker can exploit this by sending a crafted HTTP DELETE request with a user-controlled 'object_name' path parameter. This allows for the unauthorized deletion of arbitrary objects/files within the underlying MinIO storage system. The flaw is categorized under CWE-552 (Files or Directories Accessible to External Parties).
