CVE-2026-10564: IBM Langflow OSS SSRF through RSSReaderComponent and SearXNG

Summary

IBM Langflow OSS versions 1.0.0 through 1.9.6 contain a Server-Side Request Forgery flaw, tracked as CVE-2026-10564. The legacy RSSReaderComponent in rss.py and the SearXNG component in searxng.py send HTTP requests to user-controlled URLs without validation, bypassing the SSRF protections added in 1.9.3. An authenticated attacker can reach internal resources, including cloud metadata services (AWS/Azure/GCP IMDS), potentially exfiltrating IAM credentials and enumerating internal networks. Prompt injection in agentic workflows can also trigger it through tool_mode=True exposure.
