What is CVE-2026-34725?
CVE-2026-34725 is a high-severity cross-site scripting vulnerability in dbgate, published on 2 Apr 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Official description
DbGate is cross-platform database manager. From version 7.0.0 to before version 7.1.5, a stored XSS vulnerability exists in DbGate because attacker-controlled SVG icon strings are rendered as raw HTML without sanitization. In the web UI this allows script execution in another user's browser; in the Electron desktop app this can escalate to local code execution because Electron is configured with nodeIntegration: true and contextIsolation: false. This issue has been patched in version 7.1.5.
