CVE-2026-33529Public exploitNetwork attack vector

Authenticated code execution via overlapping ZIP traversal

Published Mar 26, 2026 · Updated Mar 26, 2026

Path traversal in Zoraxy before 3.3.2 allows remote authenticated users to write files outside the configuration directory. The import handler removes ../ substrings only once, letting an overlapping traversal sequence regenerate ../ and pass the conf/ prefix check. Administrative access to POST /api/conf/import is required; a malicious plugin enables code execution after a manual restart and host takeover when the Docker socket is mounted.
