GHSA-q3rw-wcj6-8cjf is a medium-severity (CVSS 6.2) Information Exposure vulnerability in cinder. A fix is available for cinder — see the affected versions and patch details below.
OpenStack Cinder LVMVolumeDriver does not zero deleted snapshots
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
GHSA-q3rw-wcj6-8cjf plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 377,166 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.
Real-World Exposure
cinderReal-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 clear_volume function in LVMVolumeDriver driver in OpenStack Cinder 2013.1.1 through 2013.1.2 does not properly clear data when deleting a snapshot, which allows local users to obtain sensitive information via unspecified vectors.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for cinder, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update cinder to 7.0.0a0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-q3rw-wcj6-8cjf 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-q3rw-wcj6-8cjf can be triaged on real exposure rather than presence alone.
Tailored to GHSA-q3rw-wcj6-8cjf. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
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.
