CVE-2026-73197
Full vulnerability record from the local CVENow database.
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.
Severity

"value": "Se encontró una falla en FreeIPA. Un atacante remoto no autenticado puede explotar esta vulnerabilidad enviando solicitudes POST de formulario sobredimensionadas al endpoint “/ipa/migration/migration.py”. Esto puede forzar al gestor de migración a leer cuerpos de solicitud controlados por el atacante completamente en memoria, lo que lleva a un mayor uso de memoria, un manejo de solicitudes más lento y una posible interrupción del servicio o denegación de servicio."
