dbgate-webnpmDescription
A security vulnerability has been detected in DbGate up to 7.1.4. This affects an unknown function of the file packages/web/src/icons/FontIcon.svelte of the component SVG Icon String Handler. Such manipulation of the argument applicationIcon leads to cross site scripting. The attack may be launched remotely. The exploit has been disclosed publicly and may be used. Upgrading to version 7.1.5 mitigates this issue. It is advisable to upgrade the affected component.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for dbgate-web. 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 dbgate-web to 7.1.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-6216 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-2026-6216 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-2026-6216. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
