CVE-2026-45089Public exploitNetwork attack vector

Unauthenticated file creation and corruption via output path

Published May 27, 2026 · Updated May 27, 2026

Path injection in HAHWUL Dalfox before 2.13.0 allows remote attackers to create or append host files through the REST scan API. The API binds output, output-all, and debug from JSON into model.Options, and DalLog opens the supplied path outside its IsLibrary guard. The default REST server configuration uses no API key; writes contain scan log lines and remain limited to paths writable by the Dalfox process.
