GHSA-f7cr-7c2c-fm8r
HIGHGHSA-f7cr-7c2c-fm8r is a high-severity (CVSS 7.5) Information Exposure vulnerability in ironic. O3 Security confirms whether GHSA-f7cr-7c2c-fm8r is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
OpenStack Ironic Exposure of Sensitive Information to an Unauthorized Actor
Blast Radius
ironic🐍ironicReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
Description
The ironic-api service in OpenStack Ironic before 4.2.5 (Liberty) and 5.x before 5.1.2 (Mitaka) allows remote attackers to obtain sensitive information about a registered node by leveraging knowledge of the MAC address of a network card belonging to that node and sending a crafted POST request to the v1/drivers/$DRIVER_NAME/vendor_passthru resource.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐍PyPI | ironic | all versions | 4.2.5 |
| 🐍PyPI | ironic | ≥ 5.0&&< 5.1.2 | 5.1.2 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ironic. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update ironic to 4.2.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-f7cr-7c2c-fm8r 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.
How O3 protects you
O3 pinpoints whether GHSA-f7cr-7c2c-fm8r is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-f7cr-7c2c-fm8r. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-f7cr-7c2c-fm8r in your dependencies?
O3 detects GHSA-f7cr-7c2c-fm8r across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
