CVE-2026-77085Network attack vector

Internal response read via raw HTTP client

Published Aug 20, 2026 · Updated Aug 20, 2026

SSRF in the SearXNG Agent tool in n8n before 2.34.1 and 2.33.x before 2.33.4 allows remote authenticated users to read internal HTTP responses. The tool accepts a user-supplied SearXNG API URL and fetches it with a raw HTTP client instead of n8n's centralized SSRF-protected request path, bypassing the N8N_SSRF_PROTECTION_ENABLED control. Exploitation requires permission to create SearXNG credentials and configure a personal agent, and the disclosed consequence is limited to server-side requests whose response bodies are returned in Agent chat output.
