CVE-2026-30973Public exploitNetwork attack vector

Arbitrary file write via nonfunctional traversal check

Published Mar 10, 2026 · Updated Mar 10, 2026

Path traversal in Appium @appium/support before 7.0.6 allows remote attackers to write files via a crafted ZIP archive. ZipExtractor.extract() joins each entry name to the destination, but its boundary check merely constructs an Error instead of throwing it before extractEntry() writes the file. Extraction must be initiated by a user or automation system, and writes are limited to locations writable by the Appium process.
