Vaadin vulnerable to possible information disclosure of class and method names in RPC response

CVE-2023-25500GHSA-ch48-9r3q-pv7x

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (com.vaadin:flow-server 24.1.0, 24.0.9, 23.3.13, 9.1.2, 2.9.3, 1.0.21; com.vaadin:vaadin 24.1.0, 24.0.7, 23.3.14, 22.1.0, 14.10.2, 10.0.24), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

# Patch Next advisory brief: CVE-2023-25500

Advisory: Vaadin vulnerable to possible information disclosure of class and method names in RPC response
IDs: CVE-2023-25500, GHSA-ch48-9r3q-pv7x
Record: https://patchnext.com/advisories/cve-2023-25500 (revision 1, source checked 26 Oct 2026, 16:19 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Low (CVSS 3.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: com.vaadin:flow-server 24.1.0, 24.0.9, 23.3.13, 9.1.2, 2.9.3, 1.0.21; com.vaadin:vaadin 24.1.0, 24.0.7, 23.3.14, 22.1.0, 14.10.2, 10.0.24. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven com.vaadin:flow-server: affected >= 1.0.0, < 1.0.21; >= 1.1.0, < 2.9.3; >= 3.0.0, < 9.1.2; >= 23.0.0, < 23.3.13; >= 24.0.0, < 24.0.9; >= 24.1.alpha1, < 24.1.0; fixed in 2.9.3, 23.3.13, 1.0.21, 9.1.2, 24.1.0, 24.0.9
- Maven com.vaadin:vaadin: affected >= 10.0.0, < 10.0.24; >= 11.0.0, < 14.10.2; >= 15.0.0, < 22.1.0; >= 23.0.0, < 23.3.14; >= 24.0.0, < 24.0.7; >= 24.1.0.alpha1, < 24.1.0; fixed in 24.0.7, 10.0.24, 22.1.0, 14.10.2, 23.3.14, 24.1.0

## Suggested inspection (read-only)
- Maven com.vaadin:flow-server: check the installed version with your package manager.
- Maven com.vaadin:vaadin: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on com.vaadin:flow-server, com.vaadin:vaadin.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
