CVE-2026-73198

A flaw was found in FreeIPA. A remote, unauthenticated attacker can exploit a vulnerability in the /ipa/i18nmessages 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 o...

GHSA-V828-M3PF-VQ9Q New API: Unauthenticated payment webhooks allow memory and disk DoS via unbounded body reads and full-body logging

Summary Unauthenticated payment webhook endpoints could read and log the entire request body before validating the webhook signature. When a payment webhook was enabled, an unauthenticated attacker could send oversized requests to public callback endpoints and force excessive memory use and log...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the island renderer endpoint when attacker-controlled input is decoded and hashed before URL-resident hash validation. An attacker can exhaust CPU resources and degrade or stall t...
