IBM Langflow OSS 1.0.0 through 1.10.0 could allow a remote attacker to overwrite administrator email information and abuse the server as an outbound relay due to missing authentication for the registration endpoint.

IBM Langflow OSS 1.0.0 through 1.10.0 allows an authenticated attacker to create a malicious flow pointing to an attacker-controlled URL that returns a specially crafted Content-Disposition header (e.g., filename="../../../target/path" ), enabling arbitrary file write operations with attacker-controlled content to any path accessible by the Langflow process.

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.

IBM Langflow OSS 1.0.0 through 1.10.0 allows authenticated users to override component parameters at runtime via the API. A critical security flaw exists in the parameter filtering mechanism within the applytweaks() function.

IBM Langflow OSS 1.0.0 through 1.10.0 Langflow 1.9.0 could allow server-side request forgery (SSRF) due to insecure default configuration and incomplete enforcement of the SSRF protection mechanism.

IBM Langflow OSS 1.0.0 through 1.10.0 allows an authenticated attacker to read arbitrary files including the JWT signing key and forge authentication tokens for any user.
