GHSA-v6gv-fg46-h89j
GHSA-v6gv-fg46-h89j is a security vulnerability in put. O3 Security confirms whether GHSA-v6gv-fg46-h89j is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Sensitive Data Exposure in put
Real-World Exposure
putReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects npm packages — download data is not available via public APIs for these ecosystems.
Description
All versions of put are vulnerable to Uninitialized Memory Exposure. The package incorrectly calculates the allocated Buffer size and does not trim the bytes written, which may allow attackers to access uninitialized memory containing sensitive data. This vulnerability only affects versions of Node.js <=6.x.
Recommendation
Upgrade your Node.js version or consider using an alternative package.
Affected Packages

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for put. 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 put has shipped for GHSA-v6gv-fg46-h89j 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-v6gv-fg46-h89j 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-v6gv-fg46-h89j. 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-v6gv-fg46-h89j in your dependencies?
O3 detects GHSA-v6gv-fg46-h89j across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
