GHSA-2c6h-4899-wjxr
scaly: Multiple soundness issues in Rust safe APIs
Blast Radius
scalyReal-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 contain multiple safe APIs that can trigger undefined behavior:
Array<T>::indexcan perform an out-of-bounds read.String::get_lengthcan perform an out-of-bounds read.String::append_charactercan perform an invalid write.String::to_c_stringcan perform an out-of-bounds write.
These issues were reproduced against scaly 0.0.37 under Miri. The crate is unmaintained.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for scaly. 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 scaly has shipped for GHSA-2c6h-4899-wjxr 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-2c6h-4899-wjxr 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-2c6h-4899-wjxr. 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-2c6h-4899-wjxr in your dependencies?
O3 detects GHSA-2c6h-4899-wjxr 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.
