Blast Radius
Weekly download volume for affected packages — a proxy for how broadly this vulnerability is deployed.
lockfile-lint-apinpmDescription
Versions of the package lockfile-lint-api before 5.9.2 are vulnerable to Incorrect Behavior Order: Early Validation via the resolved attribute of the package URL validation which can be bypassed by extending the package name allowing an attacker to install other npm packages than the intended one.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for lockfile-lint-api. 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 lockfile-lint-api to 5.9.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-4759 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-2025-4759 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-2025-4759. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
