GHSA-jcr6-4frq-9gjj — users
GHSA-jcr6-4frq-9gjj is a security vulnerability in users. No vendor fix is recorded yet; mitigation options are listed below.
Users vulnerable to unaligned read of `*const *const c_char` pointer
Real-World Exposure
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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-jcr6-4frq-9gjj can be triaged on real exposure rather than presence alone.
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 Security finds GHSA-jcr6-4frq-9gjj across crates.io dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
