Description
IBM Langflow OSS 1.0.0 through 1.9.6 contains a Server-Side Request Forgery (SSRF). The legacy RSSReaderComponent in rss.py and SearXNG component in searxng.py make unvalidated HTTP requests to user-controlled URLs, bypassing SSRF protections introduced in version 1.9.3. An authenticated attacker can exploit this to access internal resources including cloud metadata services (AWS/Azure/GCP IMDS), potentially exfiltrating IAM credentials and enumerating internal networks. The vulnerability can also be triggered through prompt injection in agentic workflows due to tool_mode=True exposure.
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 1.9.6. Two building blocks, the older RSS news feed reader and the SearXNG web search block, send web requests to any address a user gives them. This gets around safety checks added in version 1.9.3. Someone with a login could use this to reach internal systems, including cloud services that hold server details. They could possibly steal cloud access credentials and map your internal network. Hidden instructions in text that an AI agent workflow reads can also trigger it. This flaw is rated High.
