Description
IBM Langflow OSS 1.0.0 through 1.12.2 could allow a remote authenticated attacker to execute arbitrary code due to improper input validation.
Description quoted from the NVD record.
Who is affected
This flaw affects Langflow (also called IBM Langflow OSS), a tool for building apps that use AI language models. Versions 1.0.0 through 1.12.2 are affected. Because the product does not properly check some of the information it receives, an attacker who can log in to your Langflow installation over a network could run any code they choose on the computer where it runs. This flaw is rated High.
What to do
- Find out who installed or runs Langflow for your organization: someone on your staff, or an IT provider or vendor who manages it for you.
- If your Langflow is any version from 1.0.0 through 1.12.2, treat it as affected. No fixed version is named for this flaw yet, so check the vendor advisory linked on this page for a fixed release.
- When a fixed release is available, have the person who runs Langflow update to it.
- If an IT provider or vendor runs Langflow for you, send them this advisory and ask when the update will be done.
