Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ironic, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update ironic to 35.0.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-42510 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
To mitigate this issue, avoid enabling the console interface in OpenStack Ironic if it is not strictly required for your operational needs. If the console interface is enabled, ensure that access to the OpenStack Ironic service is restricted to trusted administrative networks to prevent unauthorized `ipmitool` command execution. Any changes to Ironic configuration may require a service restart to take effect, which could impact ongoing bare metal provisioning operations.Source: Red Hat security advisory for CVE-2026-42510 (CC BY 4.0)
