GHSA-hx3r-jv9q-85jw
HIGHGHSA-hx3r-jv9q-85jw is a high-severity (CVSS 7.5) Uncontrolled Resource Consumption vulnerability in bcoin. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether GHSA-hx3r-jv9q-85jw is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Bitcoin Inventory Out-of-Memory Denial-of-Service Attack (CVE-2018-17145)

bcoinReal-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
There was an easily exploitable uncontrolled memory resource consumption denial-of-service vulnerability that existed in the peer-to-peer network code of three implementations of Bitcoin and several alternative chains.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for bcoin. 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.
Fix
Update bcoin to 1.0.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-hx3r-jv9q-85jw is resolved across your whole dependency graph.
Workarounds
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-hx3r-jv9q-85jw 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-hx3r-jv9q-85jw. 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-hx3r-jv9q-85jw in your dependencies?
O3 detects GHSA-hx3r-jv9q-85jw across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
