GHSA-ghc8-5cgm-5rpf
Inventory fails to prohibit standard library access prior to initialization of Rust standard library runtime
Blast Radius
inventoryReal-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
Affected versions allow arbitrary caller-provided code to execute before the lifetime of main.
If the caller-provided code accesses particular pieces of the standard library that require an initialized Rust runtime, such as std::io or std::thread, these may not behave as documented. Panics are likely; UB is possible.
The flaw was corrected by enforcing that only code written within the inventory crate, which is guaranteed not to access runtime-dependent parts of the standard library, runs before main. Caller-provided code is restricted to running at compile time.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for inventory. 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 inventory to 0.2.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-ghc8-5cgm-5rpf 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 GHSA-ghc8-5cgm-5rpf 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-ghc8-5cgm-5rpf. 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-ghc8-5cgm-5rpf in your dependencies?
O3 detects GHSA-ghc8-5cgm-5rpf 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.
