GHSA-6fcr-9h9g-23fq is a medium-severity (CVSS 5.9) vulnerability in ipfs-bitswap. O3 Security confirms whether GHSA-6fcr-9h9g-23fq is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Denial of Service in ipfs-bitswap
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
ipfs-bitswapnpmDescription
Versions of ipfs-bitswap prior to 0.24.1 are vulnerable to Denial of Service (DoS). The package put unwanted blocks in the blockstore, which could be used to exhaust system resources in specific conditions.
Recommendation
Upgrade to version 0.24.1 or later.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ipfs-bitswap. 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 ipfs-bitswap to 0.24.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-6fcr-9h9g-23fq 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-6fcr-9h9g-23fq 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-6fcr-9h9g-23fq. 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-6fcr-9h9g-23fq in your dependencies?
O3 detects GHSA-6fcr-9h9g-23fq across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
