GHSA-f95p-4cv5-8w8x — linkme
GHSA-f95p-4cv5-8w8x is a security vulnerability in linkme. A fix is available for linkme — see the affected versions and patch details below.
linkme fails to ensure slice elements match the slice's declared type
Real-World Exposure
linkmeReal-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 populating a DistributedSlice of T with elements of an arbitrary other type that coerces to T. For example, elements of type &&str could end up in a slice of type [&str], since &&str coerces to &str via a deref coercion.
The flaw was corrected by implementing typechecking for distributed slice elements in such a way that coercion no longer occurs. The element's type must be a subtype of the slice's declared element type.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for linkme, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update linkme to 0.3.24 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-f95p-4cv5-8w8x 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-f95p-4cv5-8w8x can be triaged on real exposure rather than presence alone.
Tailored to GHSA-f95p-4cv5-8w8x. 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-f95p-4cv5-8w8x in your dependencies?
O3 Security finds GHSA-f95p-4cv5-8w8x across crates.io dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
