Fix: RustSec/advisory-db#2428GHSA-wwxp-hxh6-8gf8 is a security vulnerability in binary_vec_io. No vendor fix is recorded yet; mitigation options are listed below.
binary_vec_io access memory out-of-bounds in binary_read_to_ref and binary_write_from_ref
Real-World Exposure
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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-wwxp-hxh6-8gf8 can be triaged on real exposure rather than presence alone.
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 Security finds GHSA-wwxp-hxh6-8gf8 across crates.io dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
