GHSA-82w8-qh3p-5jfq
HIGHCVE-2026-54283request.form() accepts maxfields and maxpartsize to bound resource consumption while parsing form data. These limits are enforced for multipart/form-data, but silently ignored for application/x-www-form-urlencoded. An unauthenticated attacker can therefore send a urlencoded body with an arbitrarily large number of fields or an arbitrarily large field, even when the application configured limits it
