Detailed vulnerability description
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to allocation of resources without limits or throttling in the fetch adapter when processing requests and responses with configured finite size limits. A remote attacker can supply an oversized response, a large data: URL, or an oversized request body to cause a denial of service.
The issue affects server-side usage where applications rely on maxContentLength or maxBodyLength being enforced by the fetch adapter.
