CVE-2026-42866

Tookie is a advanced OSINT information gathering tool.

Published May 11, 2026 · updated Jun 17, 2026

Tookie is a advanced OSINT information gathering tool. Prior to 4.1fix, modules/modules.py's write_txt, write_csv, write_json, and (commented-but-shipping) scan_file helpers open their output as open(f"{user}. "), where user comes unsanitized from the -u CLI flag or any line of a -U usernames file. A username that contains path-separator sequences (.., /, \, or an absolute path) causes tookie-osint to write the scan output to an arbitrary path the invoking user has write permission for. This vulnerability is fixed in 4.1fix.
