CVE-2022-29567 is a medium-severity (CVSS 5.7) Information Exposure vulnerability in com.vaadin:vaadin. O3 Security confirms whether CVE-2022-29567 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Real-World Exposure
com.vaadin:vaadin☕com.vaadin:vaadin☕com.vaadin:vaadin☕com.vaadin:vaadin-grid-flow☕com.vaadin:vaadin-grid-flow☕com.vaadin:vaadin-grid-flowReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
The default configuration of a TreeGrid component uses Object::toString as a key on the client-side and server communication in Vaadin 14.8.5 through 14.8.9, 22.0.6 through 22.0.14, 23.0.0.beta2 through 23.0.8 and 23.1.0.alpha1 through 23.1.0.alpha4, resulting in potential information disclosure of values that should not be available on the client-side.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.vaadin:vaadin. 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 com.vaadin:vaadin to 14.8.10 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-29567 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-2022-29567 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-2022-29567. 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-2022-29567 in your dependencies?
O3 detects CVE-2022-29567 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
