A flaw was found in FreeIPA. A remote, unauthenticated attacker can exploit a vulnerability in the /ipa/i18n_messages endpoint by sending an arbitrarily large request body. This can cause the service to consume excessive memory, leading to memory exhaustion, degraded responsiveness, and a denial of service (DoS) condition.
