Dify: Unauthenticated Server-Side Request Forgery (SSRF) in remote file upload
Summary
Dify, an open-source LLM app development platform, contains an unauthenticated Server-Side Request Forgery (SSRF) flaw in the /console/api/remote-files/upload endpoint. An remote attacker can make the Dify server fetch arbitrary URLs, including internal services and cloud metadata endpoints, without logging in. This can expose sensitive data and let the server be used as a network pivot. CISA SSVC rates exploitation as proof-of-concept, automatable: yes, and technical impact as partial.
Affected
- Dify versions before 1.13.0
Fixed in
- Dify 1.13.0 (fix is referenced in the CVE record and the vendor release)
Workaround
- No vendor workaround published.
- Third-party suggestion: restrict access to the affected path with a reverse proxy so only authenticated users can reach it. Verify that legitimate console use still works.
- General SSRF control (suggestion, not from the vendor): restrict outbound requests from the Dify host, especially to cloud metadata addresses and internal network ranges.
Exploitation
- CISA SSVC: exploitation status 'poc' (proof of concept exists), automatable: yes.
- No known exploitation in the wild found; not listed in KEV according to one source.
- Authentication is not required for the vulnerable endpoint.
Our recommendation
- Inventory all Dify instances, including test and shadow deployments, and record their versions.
- Upgrade to Dify 1.13.0 or later as soon as possible.
- Until the upgrade is done, restrict access to the affected endpoint and review outbound traffic from the Dify host.
- If a vulnerable instance was reachable from untrusted networks, rotate any cloud credentials attached to the host and review logs for unusual outbound requests.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.

Original description (NVD)
Dify is an open-source LLM app development platform. Prior to 1.13.0, the /console/api/remote-files/upload endpoint in api/controllers/web/remote_files.py accepted an attacker-controlled URL without authentication and caused the Dify server to retrieve it. A remote attacker could use the endpoint to send requests to internal services or cloud metadata endpoints, potentially exposing sensitive data and using the server as a network pivot. This issue is fixed in version 1.13.0.
