GHSA-g662-qq45-ppwm is a medium-severity (CVSS 5.4) Cross-site Scripting (XSS) vulnerability in smoothie. 3 public exploit references exist, so weaponization risk is real. O3 Security confirms whether GHSA-g662-qq45-ppwm is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Smoothie vulnerable to Cross-site Scripting when tooltipLabel or strokeStyle are controlled by users
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.
smoothienpmDescription
The package smoothie from 1.31.0 and before 1.36.1 are vulnerable to Cross-site Scripting (XSS) due to improper user input sanitization in strokeStyle and tooltipLabel properties. Exploiting this vulnerability is possible when the user can control these properties.
Affected Packages

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for smoothie. 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 smoothie to 1.36.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-g662-qq45-ppwm 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-g662-qq45-ppwm 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-g662-qq45-ppwm. 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-g662-qq45-ppwm in your dependencies?
O3 detects GHSA-g662-qq45-ppwm across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
