CVE-2026-85699 Details
Description
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.
A server-side request forgery (SSRF) vulnerability has been identified in Jina AI Reader. This issue arises because URL validation is only applied to the initial request and not to subsequent redirect hops. As a result, attackers can create a public URL that redirects to internal network addresses or cloud metadata endpoints. When the server fetches these redirected responses, the content is returned to the attacker, potentially exposing sensitive information.
To address this vulnerability, the URL validation process should be applied to each redirect hop before fetching the final response. Additionally, connections should be pinned to validated IPs to prevent DNS rebinding attacks.
