CVE-2026-9130 Detail

Description

IBM Langflow OSS 1.0.0 through 1.10.3 contain an authorization bypass vulnerability in the MemoryComponent that allows authenticated users to access chat history of other users via session_id collision. The MemoryComponent.retrieve_messages and store_message methods filter on session_id without validating flow_id or user_id ownership, enabling cross-user information disclosure through multiple authenticated API endpoints including /api/v1/run/*, /api/v1/responses, and /api/v2/workflow/*. This vulnerability only affects multi-user deployments with LANGFLOW_AUTO_LOGIN=False.
