CVE-2026-10564
SSRF Vulnerability in Langflow OSS Legacy Components Bypasses Protection
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.

Action Type Old Value New Value Added Translation Title: Langflow OSS de IBM, Description: IBM Langflow OSS 1.0.0 hasta 1.9.6 contiene una falsificación de petición del lado del servidor (SSRF). El componente heredado RSSReaderComponent en rss.py y el componente SearXNG en searxng.py realizan peticiones HTTP no validadas a URLs controladas por el usuario, eludiendo las protecciones de SSRF introducidas en la versión 1.9.3. Un atacante autenticado puede explotar esto para acceder a recursos internos, incluyendo servicios de metadatos en la nube (AWS/Azure/GCP IMDS), exfiltrando potencialmente credenciales de IAM y enumerando redes internas. La vulnerabilidad también puede ser activada a través de inyección de prompts en flujos de trabajo agénticos debido a la exposición de tool_mode=True. -
