CVE-2026-42866— Tookie: Arbitrary file write via path traversal in -u username / -U userfile output filename

Tookie: Arbitrary file write via path traversal in -u username / -U userfile output filename

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}.<ext>"), 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.

N/A

对路径名的限制不恰当(路径遍历)

Tookie-OSINT 路径遍历漏洞

Tookie-OSINT是alfredredbird个人开发者的一款跨平台用户名发现工具。 Tookie-OSINT 4.1fix之前版本存在路径遍历漏洞，该漏洞源于modules/modules.py中write_txt、write_csv、write_json和scan_file辅助函数将用户输入直接用作文件名，可能导致包含路径分隔符的用户名导致扫描输出写入任意路径。
