What to do

AI-suggested

Red Hat has released updated OpenShift Virtualization v4.12 images that include fixes and enhancements. Users should ensure all previously released errata are applied before updating. Although patches are available upstream in Axios, Red Hat notes that in some OpenShift components the vulnerability is not exploitable due to runtime constraints. Users should apply the updated images as per Red Hat's advisory instructions. No additional mitigation is required where the vulnerable component is not shipped or not exploitable. Refer to Red Hat advisory RHSA-2026:53676 for detailed update procedures.

Description

CVE-2026-40175 is a prototype pollution vulnerability in the Axios HTTP client library that can be escalated via specific gadget attack chains in third-party dependencies. This flaw potentially allows remote code execution or full cloud compromise, including bypassing AWS IMDSv2 protections. Red Hat products incorporating the vulnerable Axios library are affected, but the vulnerability is not exploitable in certain OpenShift components due to runtime environment constraints. The flaw is mitigated in some contexts by patches in Axios, but residual risks remain due to HTTP header sanitation and SSRF threats.
