Description
IBM Langflow OSS 1.0.0 through 1.10.3 could allow a remote attacker to inject arbitrary code on the system, due to the improper control of user input code.
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. It affects versions 1.0.0 through 1.10.3. Because a part of the product does not properly control code that users put into it, an attacker working over the network could inject code of their choosing on the computer where Langflow is installed. If your organization runs any of these versions, it is affected. This flaw is rated High.
What to do
- Find out who runs Langflow for your organization: the person who installed it, or the IT provider or vendor who manages it for you.
- Have that person check which version of Langflow is in use. Versions 1.0.0 through 1.10.3 are affected.
- No fixed version is named for this flaw yet, so check the vendor advisory linked on this page for a fixed release and install it as soon as one is available.
- If an IT provider or vendor runs Langflow for your organization, send them this advisory and ask when the update will be done.
