CVE-2026-85699
jina-ai reader contains a server-side request forgery vulnerability where URL validation is performed only on the initial request but not re-applied to subsequent redirect hops. Attackers can craft a public URL that redirects to internal network addresses or cloud metadata endpoints, allowing the server to fetch and return the target's response body to the attacker.
What this means for your business
- An attacker can use it remotely, over a network, without a login, and without anyone at your company clicking anything.
