NVD description
n8n before 2.34.1 and 2.33.x before 2.33.4 contains an SSRF protection bypass in the SearXNG Agent tool. The tool sent requests to the user-supplied API URL using a raw HTTP client that did not route through n8n's centralized SSRF protection. On instances with N8N_SSRF_PROTECTION_ENABLED=true, an authenticated user with permission to create SearXNG credentials and configure a personal agent could set the API URL to an internal host, causing the n8n server to connect to that host and return the response content through the Agent chat output.
What to do
- Upgrade n8n to
2.33.4or later. - Do not expose the component's API or UI to the internet without authentication in front of it.
