Description
IBM Langflow OSS 1.0.0 through 1.10.0 Langflow could allow remote code execution due to incomplete validation enforcement on MCP server configuration files.
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. The problem is in how Langflow checks the settings files that connect it to outside tool servers (known as MCP servers): those checks are incomplete. Because of this, an attacker could run their own commands on the computer where Langflow is installed. This flaw is rated High. If your organization uses Langflow in any of these versions, this problem matters to you.
What to do
- Find out who installed or runs Langflow for your organization: a staff member, a volunteer, or an IT provider or vendor. That person or company should act on this advisory.
- Have them check which version of Langflow is in use. Versions 1.0.0 through 1.10.0 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 it is available.
- If an IT provider or vendor runs Langflow for you, send them this advisory and ask when the update will be done.
