CVE-2026-34725: dbgate-web: Stored XSS in applicationIcon leads to potential RCE in Electron due to unsafe renderer configuration

April 1, 2026 (updated April 6, 2026)

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.
