NVD description

IBM Langflow OSS 1.0.0 through 1.12.3 could allow an authenticated attacker to produce a server-generated ZIP archive containing entry paths that traverse outside the intended extraction directory. Extraction of the archive by a victim using a non-sanitizing tool could result in arbitrary file write on the victim's host.

What to do

  • Upgrade Langflow to 1.12.4 or later.
  • Do not expose the component's API or UI to the internet without authentication in front of it.
