CVE-2026-73197 (GCVE-0-2026-73197)

Title
Ipa: freeipa: unauthenticated dos in `/ipa/migration/migration.py` via unbounded request body read
Summary
A flaw was found in FreeIPA. A remote, unauthenticated attacker can exploit this vulnerability by sending oversized form POST requests to the `/ipa/migration/migration.py` endpoint. This can force the migration handler to read attacker-controlled request bodies fully into memory, leading to increased memory usage, slower request handling, and potential service disruption or denial of service.
