safe_pqc_kyber leaks parts of secret keys
Real-World Exposure
safe_pqc_kyberReal-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
Impact
On some platforms, when an attacker can time decapsulation, and in particular when the attacker can forge cipher texts, they can learn (parts of) the secret key.
Does not apply to ephemeral usage, such as when used in the regular way in TLS.
Patches
Patched in 0.6.2.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for safe_pqc_kyber, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update safe_pqc_kyber to 0.6.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-p4v8-jgcv-9g75 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-p4v8-jgcv-9g75 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-p4v8-jgcv-9g75. 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-p4v8-jgcv-9g75 in your dependencies?
O3 Security finds GHSA-p4v8-jgcv-9g75 across crates.io dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
