CVE-2026-91199

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.

What this means for your business

  • An attacker can use it remotely, over a network, with an ordinary user login, and without anyone at your company clicking anything.

What to do

  1. 1Ask your IT team or provider whether any of your systems use the affected product.
  2. 2If you do, follow the vendor's guidance. No patch reference has been published yet.
