Vulnerability details
The vulnerability allows a remote user to disclose sensitive information from internal services.
The vulnerability exists due to improper access control in the SearXNG Agent tool when sending requests to a user-supplied API URL during agent search execution. A remote user can configure a SearXNG credential that points to an internal host and trigger the agent to read internal service responses to disclose sensitive information from internal services.
Only instances with N8N_SSRF_PROTECTION_ENABLED=true are affected, and exploitation requires permission to create SearXNG credentials and configure a personal agent.
