Summary
Vaadin vulnerable to Cross-site Scripting
Action captions in Vaadin accept HTML by default but were not sanitized, potentially allowing Cross-site Scripting (XSS) if caption content is derived from user input.
In Vaadin Framework 7 and 8, the Action class is a general-purpose class that may be used by multiple components. The fixed versions sanitize captions by default and provide an API to explicitly enable HTML content mode for backwards compatibility.
In Vaadin 23 and newer, the Action class is only used by the Spreadsheet component. The fixed versions sanitize HTML using Jsoup with a relaxed safelist.
Vaadin 14 is not affected as Spreadsheet component was not supported.
Users of affected versions should apply the following mitigation or upgrade. Releases that have fixed this issue include:

Impact
Untrusted input is rendered as active markup in a victim's browser, which can run script in their session. Typical impact: session or credential theft, and actions taken as the user.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2025-15022? CVE-2025-15022 is a medium-severity cross-site scripting (XSS) vulnerability in com.vaadin:vaadin-server (maven), affecting versions >= 7.0.0, < 7.7.50. It is fixed in 7.7.50, 8.30.0, 23.6.6, 24.8.14, 24.9.7. Untrusted input is rendered as active markup in a victim's browser, which can run script in their session.
- Which packages are affected by CVE-2025-15022?
com.vaadin:vaadin-server(maven) (versions >= 7.0.0, < 7.7.50)com.vaadin:vaadin(maven) (versions >= 23.1.0, < 23.6.6)com.vaadin:vaadin-spreadsheet-flow(maven) (versions >= 23.1.0, < 23.6.6)
- Is there a fix for CVE-2025-15022? Yes. CVE-2025-15022 is fixed in 7.7.50, 8.30.0, 23.6.6, 24.8.14, 24.9.7. Upgrade to this version or later.
- Is CVE-2025-15022 exploitable, and should I be worried? Whether CVE-2025-15022 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2025-15022 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
