Threats affecting pkg:maven/com.vaadin/vaadin

CVE-2026-120350 is a cross-site scripting (XSS) vulnerability in the Vaadin Rich Text Editor component of vaadin-core versions 25.0.0 through 25.3.4. The issue arises because the editor exports a video embed without properly escaping its value, allowing crafted input to break out of the href attribute and execute script in the browser of any user viewing the content. This affects content persisted through the asDelta() method. Earlier versions (Vaadin 24 and older) are not affected due to different HTML handling. Fixed versions are available starting from 25.2.13 and 25.3.5.

CVE-2026-120326 is a vulnerability in Vaadin Flow's DownloadEvent.setFileName(String) method where the file name is written into the Content-Disposition header without proper escaping. This allows an attacker to inject a filename* parameter by including special characters such as double quotes in the file name, causing browsers to save the file under a name and extension chosen by the attacker. This bypasses any file name or extension restrictions enforced by the application. The vulnerability affects Vaadin Flow versions starting from 24.8.0 up to certain fixed versions. Fixed releases are available, and users should upgrade to these versions to mitigate the issue.

The push endpoint of a Vaadin application that uses server push reflects the request Origin into the Access-Control-Allow-Origin response header and allows credentials, because Flow configures Atmosphere with DROP_ACCESS_CONTROL_ALLOW_ORIGIN_HEADER set to false and its CorsInterceptor then echoes whatever Origin the request carries. A page on any origin can therefore make a cross origin request to that endpoint with the user's cookies and read the response, although reading anything useful also requires the push identifier of that session. Applications that do not use @Push are not affected, and neither is the WebSocket transport. The behaviour was introduced in January 2015 and is present in every Flow release and in Vaadin Framework from 7.1.0, which is when push was added. Users of affected versions should apply the following mitigation or upgrade. Releases that have fixed this issue include: Product version Vaadin 14.14.0 - 14.14.7 Vaadin 23.6.0 - 23.6.16 Vaadin 24.4.0 - 24.4.25 Vaadin 24.5.0 - 24.5.15 Vaadin 24.6.0 - 24.6.13 Vaadin 24.7.0 - 24.7.16 Vaadin 24.8.0 - 24.8.17 Vaadin 24.9.0 - 24.9.23 Vaadin 24.10.0 - 24.10.11 Vaadin 25.0.0 - 25.0.13 Vaadin 25.1.0 - 25.1.13 Vaadin 25.2.0 - 25.2.10 Vaadin 25.3.0 - 25.3.2 Vaadin Framework 7.1.0 - 7.7.54 Vaadin Framework 8.0.0 - 8.32.1 Mitigation Upgrade to 14.14.8 Upgrade to 23.6.17 Upgrade to 24.4.26 Upgrade to 24.7.17 Upgrade to 24.7.17 Upgrade to 24.7.17 Upgrade to 24.9.24 Upgrade to 24.9.24 Upgrade to 24.10.12 Upgrade to 25.2.11 Upgrade to 25.2.11 Upgrade to 25.2.11 Upgrade to 25.3.3 Upgrade to 7.7.55 Upgrade to 8.32.2 Please note that Vaadin versions 10-13 and 15-22 are no longer supported and you should update either to the latest 14, 23, 24, 25 version.

CVE-2026-107588 is a high-severity cross-site scripting (XSS) vulnerability in Vaadin Charts, which uses a pinned version of the Highcharts library. The vulnerability arises from multiple vectors in the chart configuration, including Object.prototype writes via series.keys paths and XSS through credits.href, breadcrumbs.style, HTML text parsing during printing, and xlink:href attributes in exported charts. Applications are vulnerable if attacker-controlled data reaches these chart configuration options. Vaadin has released fixed versions that apply Highsoft's recommended workarounds while keeping the same Highcharts versions.

Specially crafted ZIP archives can escape the intended extraction directory during Node.js download and extraction in Vaadin 14.2.0 through 14.14.0, 23.0.0 through 23.6.6, 24.0.0 through 24.9.8, and 25.0.0 through 25.0.2. Vaadin’s build process can automatically download and extract Node.js if it is not installed locally. If an attacker can intercept or control this download via DNS hijacking, a MITM attack, a compromised mirror, or a supply chain attack, they can serve a malicious archive containing path traversal sequences that write files outside the intended extraction directory. Users of affected versions should use a globally preinstalled Node.js version compatible with their Vaadin version, or upgrade as follows: 14.2.0-14.14.0 to 14.14.1, 23.0.0-23.6.6 to 23.6.7, 24.0.0-24.9.8 to 24.9.9, and 25.0.0-25.0.2 to 25.0.3 or newer. Please note that Vaadin versions 10-13 and 15-22 are no longer supported and you should update either to the latest 14, 23, 24, 25 version.
