Refly through 1.1.0 contains a server-side request forgery vulnerability in the POST /v1/misc/scrape endpoint that fetches caller-supplied URLs without validating the scheme, host, or resolved address. Authenticated attackers can make the backend issue requests to loopback, private, and link-local addresses including cloud metadata services to read page titles and descriptions of internal resources.

Why it matters

Internet-facing
Not identified as a common internet-facing category
Exploitation likelihood
high
  • Remotely exploitable over the network — no physical or local access required
  • Low attack complexity — no special conditions needed to exploit
  • Requires low-privilege access first
  • No user interaction needed — can be exploited automatically
Recommended mitigation

Apply the vendor patch as soon as it's available or already released. Review and restrict accounts with the privilege level this vulnerability requires.

This analysis is generated from structured CVSS vector data, CISA KEV cross-referencing, and vendor/product category rules — not a manual expert review. Treat it as a starting point, not a substitute for your own assessment.
