Summary
dbgate-web: Stored XSS in applicationIcon leads to potential RCE in Electron due to unsafe renderer configuration
Impact
Web app
If an attacker can place a malicious application definition where another user will load it, arbitrary JavaScript executes in the victim's browser session. This can lead to token theft, session hijacking, and performing privileged actions as the victim inside DbGate.
Electron desktop app
In the desktop app, the impact is more severe because the Electron renderer is configured with nodeIntegration: true and contextIsolation: false. If a victim imports or saves a malicious application definition and later opens a UI view that renders the icon, the XSS can access Node/Electron APIs and may result in local code execution on the victim machine.
Untrusted input is rendered as active markup in a victim's browser, which can run script in their session. Typical impact: session or credential theft, and actions taken as the user.
CVE-2026-34725 has a CVSS score of 8.2 (High). The vector is requires local access, low privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (7.1.5); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2026-34725? CVE-2026-34725 is a high-severity cross-site scripting (XSS) vulnerability in dbgate-web (npm), affecting versions >= 7.0.0, < 7.1.5. It is fixed in 7.1.5. Untrusted input is rendered as active markup in a victim's browser, which can run script in their session.
- How severe is CVE-2026-34725? CVE-2026-34725 has a CVSS score of 8.2 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of dbgate-web are affected by CVE-2026-34725? dbgate-web (npm) versions >= 7.0.0, < 7.1.5 is affected.
- Is there a fix for CVE-2026-34725? Yes. CVE-2026-34725 is fixed in 7.1.5. Upgrade to this version or later.
- Is CVE-2026-34725 exploitable, and should I be worried? Whether CVE-2026-34725 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2026-34725 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
- How do I fix CVE-2026-34725? Upgrade
