A fix is available — apply it.

Vaadin Charts renders charts with the Highcharts library and pins an exact version of it, 9.2.2 in Vaadin 22 to 24 and 12.2.0 in Vaadin 25, so an application cannot remove these vulnerabilities by upgrading Highcharts on its own. Highsoft disclosed several vulnerabilities in that library that are reachable through the chart configuration: writes to Object.prototype through dotted series.keys paths, and cross-site scripting through credits.href, through breadcrumbs.style, through HTML text parsing while printing, and through xlink:href attributes in exported charts. An application is affected where data an attacker controls reaches the chart configuration, for example through additionalOptions, through updateConfiguration(), or through text options that accept markup. The fixed Vaadin versions apply Highsoft's recommended workarounds to the bundled Highcharts when it loads, and keep the same Highcharts version.

Users of affected versions should apply the following mitigation or upgrade. Releases that have fixed this issue include:

Product version Vaadin 22.0.0 - 23.6.15 Vaadin 24.0.0 - 24.4.23 Vaadin 24.5.0 - 24.7.15 Vaadin 24.8.0 - 24.9.22 Vaadin 24.10.0 - 24.10.10 Vaadin 25.0.0 - 25.2.9 Vaadin 25.3.0

Mitigation Upgrade to 23.6.16 Upgrade to 24.4.24 Upgrade to 24.7.16 Upgrade to 24.9.23 Upgrade to 24.10.11 Upgrade to 25.2.10 Upgrade to 25.3.1 or newer

Please note that Vaadin versions 10-13 and 15-22 are no longer supported and you should update either to the latest 23, 24, 25 version.

EG Risk is EchelonGraph's 0–100 priority score. It fuses impact severity (EG Severity, the CVSS base score, never the KEV-floored or EPSS-lifted EG Score) with real-world exploitation and automatability, under weights EchelonGraph set by hand, so you can rank equal-severity CVEs and fix the most dangerous first.
