CVE-2026-50589: CWE-770 Allocation of Resources Without Limits or Throttling in OpenStack Ironic
In OpenStack Ironic 32 before 37.0.0, an unauthenticated malicious user could submit a crafted JSON string to some endpoints on the API or JSON-RPC service and effect a service crash.
AI Analysis
Technical Summary
OpenStack Ironic versions >=32 and <37.0.0 contain a CWE-770 vulnerability where an unauthenticated malicious user can send a specially crafted JSON payload to some API or JSON-RPC endpoints, resulting in a denial of service via service crash. This occurs because the service allocates resources without proper limits or throttling, leading to exhaustion. The vulnerability does not impact confidentiality or integrity but affects availability. The Red Hat advisory linked does not provide explicit patch or remediation details.
Potential Impact
The vulnerability allows unauthenticated attackers to cause a denial of service by crashing the OpenStack Ironic service. This impacts the availability of the service but does not affect confidentiality or integrity. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory at https://access.redhat.com/security/cve/CVE-2026-50589 for current remediation guidance. Until an official fix is available, consider restricting access to vulnerable endpoints and monitoring for unusual JSON payloads that could trigger the crash.
