DescriptionCVE.org
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.
AnalysisAI
Cross-site scripting in DbGate's SVG Icon String Handler allows a remote authenticated attacker to inject malicious script via the applicationIcon argument in FontIcon.svelte, executing arbitrary JavaScript in a victim user's browser session. Affected versions span 7.1.0 through 7.1.4, with a confirmed fix released in v7.1.5. A public proof-of-concept exploit has been disclosed via VulDB, though EPSS at 0.03% (9th percentile) and SSVC's 'exploitation: none' designation indicate no observed active exploitation at time of analysis.
Technical ContextAI
DbGate is an open-source database management GUI that renders SVG-based icons through a Svelte component at packages/web/src/icons/FontIcon.svelte. The applicationIcon parameter fed into this SVG Icon String Handler is not adequately sanitized or encoded before being rendered into the DOM, violating CWE-79 (Improper Neutralization of Input During Web Page Generation). Because the payload is introduced through a user-configurable icon string and then reflected or persisted in the web interface, malicious script can be embedded and later executed in any browser that renders the affected component. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:P) confirms the network-based, low-complexity nature of the injection, requiring authenticated access and a victim to interact with the malicious content. The CPE cpe:2.3:a:n/a:dbgate:*:*:*:*:*:*:*:* covers all platform variants of DbGate up to the patched release.
RemediationAI
Upgrade DbGate to version 7.1.5 or later, which resolves this vulnerability per the vendor's GitHub release at https://github.com/dbgate/dbgate/releases/tag/v7.1.5. If an immediate upgrade is not feasible, administrators should restrict access to the DbGate web interface to trusted, authenticated users only through network-level controls such as firewall rules or VPN gating, reducing the exposure window since exploitation requires PR:L and UI:P. Additionally, organizations with Content Security Policy (CSP) headers configured on their DbGate deployment may be able to partially mitigate script execution; however, CSP effectiveness depends on deployment configuration and should not be treated as a complete workaround. The primary remediation is patching to v7.1.5.
