CVE-2026-50589: CWE-770 Allocation of Resources Without Limits or Throttling in OpenStack Ironic
CVE-2026-50589 is a medium severity vulnerability in OpenStack Ironic versions 32 through 35. 0. 1. It involves allocation of resources without limits or throttling, allowing an unauthenticated attacker to submit a crafted JSON string to certain API or JSON-RPC endpoints, causing a service crash. This results in a denial of service condition but does not impact confidentiality or integrity. No known exploits are reported in the wild, and no official patch or remediation guidance is currently available.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-50589) affects OpenStack Ironic versions 32 through 35.0.1 and is classified under CWE-770 (Allocation of Resources Without Limits or Throttling). An unauthenticated attacker can send a specially crafted JSON payload to some API or JSON-RPC endpoints, triggering a crash of the service. The CVSS 3.1 base score is 5.3, reflecting a network attack vector with no privileges or user interaction required, causing availability impact only. There is no indication of confidentiality or integrity impact. The vulnerability is publicly known but lacks an official fix or vendor advisory at this time.
Potential Impact
The primary impact is a denial of service due to service crash caused by resource exhaustion from crafted JSON input. There is no impact on data confidentiality or integrity. The vulnerability can be exploited remotely without authentication, potentially disrupting availability of the OpenStack Ironic service.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, consider implementing network-level protections such as rate limiting or input validation proxies to mitigate potential exploitation. Monitor for updates from the OpenStack project regarding patches or workarounds.
