CVE-2024-47829
MEDIUMCVE-2024-47829 is a medium-severity (CVSS 6.5) CWE-328 vulnerability in pnpm. O3 Security confirms whether CVE-2024-47829 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
pnpm uses the md5 path shortening function causes packet paths to coincide, which causes indirect packet overwriting
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, a proxy for how much of the ecosystem is exposed.
pnpmnpmDescription
pnpm is a package manager. Prior to version 10.0.0, the path shortening function uses the md5 function as a path shortening compression function, and if a collision occurs, it will result in the same storage path for two different libraries. Although the real names are under the package name /node_modoules/, there are no version numbers for the libraries they refer to. This issue has been patched in version 10.0.0.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for pnpm. 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 pnpm to 10.0.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-47829 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 CVE-2024-47829 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 CVE-2024-47829. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2024-47829 in your dependencies?
O3 detects CVE-2024-47829 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
