GHSA-wwxp-hxh6-8gf8
binary_vec_io access memory out-of-bounds in binary_read_to_ref and binary_write_from_ref
Blast Radius
binary_vec_ioReal-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
Safe functions accept a single &T or &mut T but multiply by n to create slices extending beyond allocated memory when n > 1.
These functions use from_raw_parts to create slices larger than the underlying allocation, violating memory safety.
The binary_vec_io repository is archived and unmaintained.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for binary_vec_io. 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 binary_vec_io has shipped for GHSA-wwxp-hxh6-8gf8 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-wwxp-hxh6-8gf8 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-wwxp-hxh6-8gf8. 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-wwxp-hxh6-8gf8 in your dependencies?
O3 detects GHSA-wwxp-hxh6-8gf8 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.
