CVE-2026-41211
CVE-2026-41211 is a security vulnerability in vite-plus. O3 Security confirms whether CVE-2026-41211 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
`vite-plus/binding` has path traversal `downloadPackageManager()` that leads to writes outside of `VP_HOME`
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.
vite-plusnpmDescription
Vite+ is a unified toolchain and entry point for web development. Prior to version 0.1.17, downloadPackageManager() accepts an untrusted version string and uses it directly in filesystem paths. A caller can supply ../ segments or an absolute path to escape the VP_HOME/package_manager/<pm>/ cache root and make Vite+ delete, replace, and populate directories outside the intended cache location. Version 0.1.17 contains a patch.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for vite-plus. 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 vite-plus to 0.1.17 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-41211 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-2026-41211 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-2026-41211. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
