CVE-2024-32027Public exploitNetwork attack vector

Unauthenticated command execution via unsanitized metadata filename

Published Apr 16, 2024 · Updated Aug 2, 2024

Command injection in kohya_ss 22.6.1 through 23.1.4 allows remote attackers to execute arbitrary commands through the Finetune GUI. The finetune_tab function appends caption_metadata_filename and other untrusted fields to a command string that os.system passes to a shell. Exploitation requires a network-accessible Gradio interface on a POSIX host; the published proof of concept does not exploit Windows.
