CVE-2026-107588 — Multiple Vulnerabilities in the Highcharts Library Bundled with Vaadin Charts

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.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.5% (30-day exploitation probability)+7
  • Technical severity (high)+6

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Vaadin @vaadin/charts, Vaadin Vaadin, Vaadin Vaadin-charts-flow…).
  2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  3. Exploitation requires user interaction: tighten email/web filtering and warn affected users.
  4. Search available logs for exploit probes matching the vulnerability class (cross-site scripting), errors and authentication anomalies.

What should defenders know first?

CVE-2026-107588 is "Multiple Vulnerabilities in the Highcharts Library Bundled with Vaadin Charts", rated High. It affects @vaadin/charts (Vaadin); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 8.4 describes technical severity. EPSS 0.52% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
