| Doc Text: |
A flaw was found in Rails Active Storage. A remote attacker can exploit this vulnerability by sending a request with a large or unbounded Range header, such as `bytes=0-`, when files are served through Active Storage's proxy delivery mode. This action can cause the server to allocate memory proportional to the file size, potentially leading to a Denial of Service (DoS) due to memory exhaustion.
