IBM Langflow OSS vulnerable to arbitrary OS command execution
IBM Langflow OSS
IBM Langflow OSS allows authenticated users to execute arbitrary operating system commands by configuring an MCP Tools component with local stdio transport. The flaw bypasses built-in administrative controls meant to restrict code interpreter actions.
disclosed CVENo confirmed exploitation, so this record is tracked as a disclosed vulnerability and not counted as an incident. It moves into the counts if CISA or the vendor confirms exploitation. Why
