GHSA-9fjq-45qv-pcm7
ruint affected by unsoundness of safe `reciprocal_mg10`
Blast Radius
ruintReal-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
The function reciprocal_mg10 is marked as safe but can trigger undefined behavior (out-of-bounds access) because it relies on debug_assert! for safety checks instead of assert!.
When compiled in release mode, the debug_assert! is optimized out, potentially allowing invalid inputs to cause memory corruption.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ruint. 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.
Remediation status
No patched version of ruint has shipped for GHSA-9fjq-45qv-pcm7 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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-9fjq-45qv-pcm7 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-9fjq-45qv-pcm7. 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-9fjq-45qv-pcm7 in your dependencies?
O3 detects GHSA-9fjq-45qv-pcm7 across crates.io dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
