This medium-severity CVE scores 6.8 under NVD CVSS v3. EPSS exploit probability: 0.3%, top 73% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

A fix is available — apply it.

Specially crafted ZIP archives can escape the intended extraction directory during Node.js download and extraction in Vaadin 14.2.0 through 14.14.0, 15.0.0 through 23.6.6, 24.0.0 through 24.9.8, and 25.0.0 through 25.0.2.

Vaadin’s build process can automatically download and extract Node.js if it is not installed locally. If an attacker can intercept or control this download via DNS hijacking, a MITM attack, a compromised mirror, or a supply chain attack, they can serve a malicious archive containing path traversal sequences that write files outside the intended extraction directory.

Users of affected versions should use a globally preinstalled Node.js version compatible with their Vaadin version, or upgrade as follows: 14.2.0-14.14.0 to 14.14.1, 15.0.0-23.6.6 to 23.6.7, 24.0.0-24.9.8 to 24.9.9, and 25.0.0-25.0.2 to 25.0.3 or newer.

Please note that Vaadin versions 10-13 and 15-22 are no longer supported and you should update either to the latest 14, 23, 24, 25 version.
