@plone/voltonpmDescription
Volto is a ReactJS-based frontend for the Plone Content Management System. Versions 16.34.0 and below, 17.0.0 through 17.22.1, 18.0.0 through 18.27.1, and 19.0.0-alpha.1 through 19.0.0-alpha.5, an anonymous user could cause the NodeJS server part of Volto to quit with an error when visiting a specific URL. This issue is fixed in versions 16.34.1, 17.22.2, 18.27.2 and 19.0.0-alpha.6.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @plone/volto. 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 @plone/volto to 16.34.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-61668 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-2025-61668 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-2025-61668. 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-2025-61668 in your dependencies?
O3 detects CVE-2025-61668 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
