Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis
How this class of weakness works · CWE-77

User input reaches a command interpreter without being fully separated from the command itself, so an attacker can append instructions of their own. Because those run with the application's privileges, it frequently means control of the host. The lasting fix is to avoid constructing commands from input — call APIs directly and pass arguments as data, never as concatenated strings.

Recommended fix High confidence

23.1.5 or later stable release

  1. 1. Ensure you have a backup of your current kohya_ss installation and any custom configurations.
  2. 2. Update to version 23.1.5 or later which contains the security fix for the command injection vulnerability in git_caption_gui.py.
  3. 3. If using pip, run: pip install kohya-ss==23.1.5 (or check for later stable releases).
  4. 4. Alternatively, pull the latest code from the repository which includes the fix: git pull https://github.com/bmaltais/kohya_ss.git
  5. 5. Verify the installation by checking the version: python -c "import kohya; print(kohya.__version__)" or checking the about section in the GUI.
  6. 6. Test that the git_caption_gui functionality works correctly after the update.
