How severe is GHSA-ghc8-5cgm-5rpf?

No CVSS score has been assigned to GHSA-ghc8-5cgm-5rpf yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-ghc8-5cgm-5rpf?

GHSA-ghc8-5cgm-5rpf affects the following packages: inventory (crates.io). Ecosystems affected: crates.io.

How do I fix GHSA-ghc8-5cgm-5rpf?

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.

How do I detect GHSA-ghc8-5cgm-5rpf in my crates.io dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for inventory, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-ghc8-5cgm-5rpf if there is no patch (or I can't update yet)?

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.

Is GHSA-ghc8-5cgm-5rpf actively exploited in the wild?

No public exploit code has been indexed for GHSA-ghc8-5cgm-5rpf yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

When was GHSA-ghc8-5cgm-5rpf published, and has it been updated?

GHSA-ghc8-5cgm-5rpf was published on September 11, 2023 and was last updated on February 10, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

🦀inventory

Real-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.
