Lifecycle Timeline
2DescriptionCVE.org
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.
AnalysisAI
Server-side request forgery in jina-ai reader allows unauthenticated remote attackers to probe internal network infrastructure and cloud metadata services by exploiting a redirect-validation gap in the URL fetching pipeline. The service validates URLs on initial submission but fails to re-validate the destination after HTTP redirects, enabling attackers to pivot from an attacker-controlled public URL to cloud instance metadata endpoints (e.g., AWS IMDS at 169.254.169.254) or RFC-1918 internal addresses, with the response body returned to the attacker. …

Vulnerability AssessmentAI
| Exploitation | No special conditions beyond network accessibility to the jina-ai reader service endpoint - exploitation requires only the ability to submit a URL to the reader API (PR:N, UI:N, AC:L). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 8.7 (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N) accurately captures the primary risk: unauthenticated network-accessible exploitation yielding high confidentiality impact with no complexity barrier. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch version has been independently confirmed at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: audit infrastructure for all jina-ai reader deployments and immediately restrict outbound network connectivity to whitelisted destinations only, or disable the service if not business-critical. …
