Possible information disclosure of environment variables in Vaadin Build Plugins via Failed Frontend Build_CVE-2026-7860

{
    "lastseen": "",
    "description": "A possible information disclosure vulnerability exists in the Vaadin Maven plugin and Vaadin Gradle plugin that exposes the full set of environment variables in build logs whenever the frontend build process exits with a non-zero status. Because the build environment may contain credentials supplied as secrets, any failed frontend build can expose those secrets in clear text in CI logs and archived build artifacts.\n\n\nUsers of affected versions should apply the following mitigation or upgrade. Releases that have fixed this issue include:\n\nProduct version\nVaadin 23.0.0 - 23.6.9\nVaadin 24.0.0 - 24.10.3\nVaadin 25.0.0 - 25.1.4\n\nMitigation\nUpgrade to 23.6.10\nUpgrade to 24.10.4 or newer\nUpgrade to 25.1.5 or newer\n\nPlease note that Vaadin versions 10-13 and 15-22 are no longer supported and you should update either to the latest 23, 24, or 25 version.\n\nArtifactsMaven coordinatesVulnerable versionsFixed versioncom.vaadin:flow-plugin-base23.0.0 - 23.6.10\u226523.6.11com.vaadin:flow-plugin-base24.0.0 - 24.10.3\u226524.10.4com.vaadin:flow-plugin-base25.0.0 - 25.1.4\u226525.1.5com.vaadin:flow-maven-plugin23.0.0 - 23.6.10\u226523.6.11com.vaadin:flow-maven-plugin24.0.0 - 24.10.3\u226524.10.4com.vaadin:flow-maven-plugin25.0.0 - 25.1.4\u226525.1.5com.vaadin:flow-gradle-plugin24.0.0 - 24.10.3\u226524.10.4com.vaadin:flow-gradle-plugin25.0.0 - 25.1.4\u226525.1.5",
