Jina Reader Private-Address Guard Bypass via SSRF

Publication date: 2026-08-30

Last updated on: 2026-08-30

Assigner: VulnCheck

Description
jina-ai reader disables its private-address guard outside Google Cloud deployments, allowing unauthenticated attackers to perform server-side request forgery. Attackers can supply publicly resolvable hostnames mapping to private addresses to retrieve cloud metadata and internal service content.

Executive Summary

CVE-2026-82638 is a Server-Side Request Forgery (SSRF) vulnerability in the jina-ai reader software. It occurs because the private-address guard is disabled outside Google Cloud deployments, allowing unauthenticated attackers to supply hostnames that resolve to private addresses and perform SSRF attacks. This lets attackers retrieve cloud metadata and access internal services.

Detection Guidance

To detect this vulnerability, check if your jina-ai reader instance is running in a self-hosted Docker deployment with default settings. Verify if the service allows requests to private/internal IP addresses via hostnames. Test by attempting to access internal services or cloud metadata endpoints using publicly resolvable hostnames that map to private addresses.

Impact Analysis

An attacker could exploit this to access internal services, including cloud metadata endpoints like AWS IMDS, potentially exposing sensitive data such as IAM credentials. The attack works on self-hosted instances with default Docker settings and requires no authentication.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR's data protection principles and HIPAA's security requirements for protected health information. Unauthorized data exposure may result in compliance breaches and legal penalties.

Mitigation Strategies

Immediately update jina-ai reader to a patched version beyond commit hash 1574bfd380d249c86c82db4dace0d9c8fe17e2b1. Ensure the environment variable NODE_ENV is set to 'prod' and GCLOUD_PROJECT is configured to enforce private-address guard. Block wildcard DNS services like nip.io in firewall rules.
