Description
IBM Langflow OSS 1.0.0 through 1.10.0 Langflow could allow disclosure of all stored credentials due to the use of a weak and reversible key derivation mechanism for encryption at rest.
Description quoted from the NVD record.
Who is affected
Langflow (also called IBM Langflow OSS) is a tool for building apps that use AI language models. This flaw affects versions 1.0.0 through 1.10.0. Langflow saves credentials, such as passwords and access keys for other services, in a scrambled form, but the way it creates the key for that scrambling is weak and can be reversed. As a result, all stored credentials could be exposed. This flaw is rated Critical.
What to do
- The person who installed or runs Langflow for your organization should check which version you use. If it is 1.0.0 through 1.10.0, it is 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 it 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.
