CVE-2022-34271Network attack vector

Arbitrary file write via unchecked ZIP paths

Published Dec 14, 2022 · Updated Apr 18, 2025

Path traversal in Apache Atlas 0.8.4 through 2.2.0 allows remote authenticated users to write files outside the import directory. ZipSourceWithBackingDirectory joins each ZIP entry name directly to its temporary extraction directory without rejecting parent-directory segments. The import API is restricted to administrators, and a crafted archive can overwrite files writable by the Atlas server process.
