CVE-2026-73197
Ipa: freeipa: unauthenticated dos in `/ipa/migration/migration.py` via unbounded request body read
CVSS 3.1
7.5High
Official description
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.
