CVE-2026-91199

Description

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.
