Who should care

Defenders responsible for CI/CD pipelines, developers using Vaadin plugins, and teams managing build artifacts should assess exposure and prioritize remediation. They should review build logs and archived artifacts for exposure of sensitive information and verify whether affected product deployments exist in managed environments. Security teams and vulnerability management teams should also be aware of the potential risks and take necessary actions to

Why it matters

CVE-2026-7860 is a possible information disclosure vulnerability in Vaadin plugins. Defenders should prioritize upgrading to fixed versions or applying mitigations to prevent potential information disclosure. Review build logs and archived artifacts for exposure of sensitive information.

  • Potential exposure of sensitive information in build logs and artifacts
  • Need to verify build logs and artifacts for sensitive information exposure
  • Prioritize upgrading to fixed versions or applying mitigations
  • Review CI/CD pipeline configurations and build artifact storage

Technical summary

The Vaadin Maven plugin and Vaadin Gradle plugin are vulnerable to information disclosure. When the frontend build process exits with a non-zero status, the full set of environment variables is exposed in build logs. This can lead to the exposure of credentials supplied as secrets in clear text in CI logs and archived build artifacts. The vulnerability exists in versions Vaadin 23.0.0 - 23.6.9, Vaadin 24.0.0 - 24.9.16, Vaadin 24.10.0 - 24.10.3, Vaadin 25.0.0 - 25.0.10, and Vaadin 25.1.0 - 25.1.4. Defenders should prioritize upgrading to fixed versions or applying mitigations to prevent potential information disclosure.

Defensive priority

Defenders should prioritize upgrading to fixed versions or applying mitigations to prevent potential information disclosure. Review build logs and archived artifacts for exposure of sensitive information.
