CVE-2026-2741 describes a path traversal vulnerability (CWE-22) in Vaadin versions 14.2.0 through 25.0.2, allowing specially crafted ZIP archives to escape their intended extraction directory. This occurs when Vaadin's build process downloads Node.js, enabling an attacker to serve a malicious archive via interception methods like MITM or supply chain attacks, though the attack complexity is high. The vulnerability has a CVSS 4.0 score of 2.3 (LOW), with a network attack vector, and its overall impact on confidentiality, integrity, and availability is rated low despite the potential for arbitrary file writes. Currently, there is no evidence of active exploitation, public exploit code, or significant community discussion, indicating a low immediate threat level.
