CVE-2026-73197

Ipa: freeipa: unauthenticated dos in `/ipa/migration/migration.py` via unbounded request body read

State: Published
Severity: 7.5 High
Published: Aug 20, 2026
Updated: Nov 2, 2026
Reserved: Aug 11, 2026

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.
