GHSA-jf5h-cf95-w759 — raw-cpuid
GHSA-jf5h-cf95-w759 is a Improper Input Validation vulnerability in raw-cpuid. A fix is available for raw-cpuid — see the affected versions and patch details below.
Optional `Deserialize` implementations lacking validation
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.
Real-World Exposure
raw-cpuidReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects crates.io packages — download data is not available via public APIs for these ecosystems.
Description
When activating the non-default feature serialize, most structs implement
serde::Deserialize without sufficient validation. This allows breaking
invariants in safe code, leading to:
- Undefined behavior in
as_string()methods (which usestd::str::from_utf8_unchecked()internally). - Panics due to failed assertions.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for raw-cpuid, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update raw-cpuid to 9.1.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-jf5h-cf95-w759 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-jf5h-cf95-w759 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-jf5h-cf95-w759. 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-jf5h-cf95-w759 in your dependencies?
O3 Security finds GHSA-jf5h-cf95-w759 across crates.io dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
