Internal service enumeration via unrestricted URL fetch
Published Sep 22, 2025 · Updated Sep 22, 2025
SSRF in Flowise 3.0.5 allows remote attackers to enumerate internal web-service links through the /api/v1/fetch-links endpoint. The fetch-links service decodes a supplied URL and passes it to webCrawl or xmlScrape, which fetches the destination without validating or restricting its network location. Exploitation requires network access to an exposed Flowise server and discloses extracted link structures rather than arbitrary internal response bodies.
