CVE-2026-107588 vaadin CVE debrief

Who should care

Defenders responsible for Vaadin applications using Vaadin Charts, particularly those in roles related to application security, vulnerability management, and software development, should assess exposure and prioritize remediation.

Why it matters

CVE-2026-107588 exposes Vaadin Charts to multiple vulnerabilities due to the bundled Highcharts library, emphasizing the need for defenders to validate chart configurations, sanitize input data, and upgrade to fixed versions to prevent potential attacks.

• Potential for attacker-controlled data to be written to Object.prototype, affecting application behavior
• Risk of cross-site scripting attacks through chart configurations, impacting user interaction with the application
• Need for validation and sanitization of chart configuration data to prevent exploitation
• Priority on upgrading to fixed Vaadin versions or applying recommended workarounds to mitigate vulnerabilities

Technical summary

The Highcharts library bundled with Vaadin Charts is vulnerable to multiple issues, including writes to Object.prototype through dotted series.keys paths and cross-site scripting through various chart configuration paths. These vulnerabilities can be exploited if an attacker can control data that reaches the chart configuration, such as through additionalOptions, updateConfiguration(), or text options that accept markup.

Defensive priority

Defenders should prioritize upgrading to fixed Vaadin versions or applying recommended workarounds, focusing on validating and sanitizing chart configuration data.

Recommended defensive actions

• Upgrade to fixed Vaadin versions (e.g., Vaadin 23.6.16, 24.4.24, 24.7.16, 24.9.23, 24.10.11) or later
• Apply Highsoft's recommended workarounds to the bundled Highcharts library
• Validate and sanitize chart configuration data to prevent attacker-controlled input from reaching the chart configuration
• Review and update affected Vaadin versions according to the vendor's security advisories
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
