GHSA-jcr6-4frq-9gjj
Users vulnerable to unaligned read of `*const *const c_char` pointer
Blast Radius
usersReal-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 dereference a potentially unaligned pointer. The pointer is commonly unaligned in practice, resulting in undefined behavior.
In some build modes, this is observable as a panic followed by abort. In other build modes the UB may manifest in some other way, including the possibility of working correctly in some architectures.
The crate is not currently maintained, so a patched version is not available.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for users. 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 users has shipped for GHSA-jcr6-4frq-9gjj 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-jcr6-4frq-9gjj 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-jcr6-4frq-9gjj. 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-jcr6-4frq-9gjj in your dependencies?
O3 detects GHSA-jcr6-4frq-9gjj 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.
