Upgrade dbgate-web to version 7.1.5 or higher.
Overview
dbgate-web is a This package is used internally by DbGate
Affected versions of this package are vulnerable to Arbitrary Code Injection through the FontIcon rendering path in packages/web/src/icons/FontIcon.svelte. An attacker can execute arbitrary JavaScript in a victim’s browser, or potentially achieve local code execution in the Electron desktop app, by supplying a malicious applicationIcon value. In the Electron desktop app, the unsafe renderer configuration (nodeIntegration: true, contextIsolation: false) allows injected scripts to access Node/Electron APIs.
**Notes**
- The attacker must be able to create, modify, or import an application definition that DbGate later loads from disk.
- The payload is triggered when a user opens a view that renders the matching database/application entry and passes
applicationIconthrough the icon rendering chain.
