CVE-2022-47951
MEDIUMCVE-2022-47951 is a medium-severity (CVSS 5.7) Path Traversal vulnerability in cinder. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether CVE-2022-47951 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
OpenStack Cinder, glance, and Nova vulnerable to Path Traversal

Description
An issue was discovered in OpenStack Cinder before 19.1.2, 20.x before 20.0.2, and 21.0.0; Glance before 23.0.1, 24.x before 24.1.1, and 25.0.0; and Nova before 24.1.2, 25.x before 25.0.2, and 26.0.0. By supplying a specially created VMDK flat image that references a specific backing file path, an authenticated user may convince systems to return a copy of that file's contents from the server, resulting in unauthorized access to potentially sensitive data.
Affected Packages

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for cinder. 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 cinder to 19.1.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-47951 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 CVE-2022-47951 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 CVE-2022-47951. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2022-47951 in your dependencies?
O3 detects CVE-2022-47951 across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
