CVE-2025-14914Network attack vector

Administrator code execution via path-traversing ZIP upload

Published Feb 2, 2026 · Updated Feb 2, 2026

Path traversal in IBM WebSphere Application Server Liberty 17.0.0.3 through 26.0.0.1 allows remote authenticated users to execute code. The REST connector's ZIP upload processing accepts path-traversing entries and writes extracted files outside the intended destination. A privileged administrator must reach an enabled restConnector-1.0 or restConnector-2.0 endpoint and complete the upload, which can overwrite server files and execute code.
