5DescriptionGitHub Advisory
FastGPT is an AI Agent building platform. Prior to version 4.14.17, an unauthenticated Server-Side Request Forgery (SSRF) vulnerability allows attackers (or authenticated users with App editing privileges) to send arbitrary HTTP requests to internal/private network addresses. The fetchData function in the lafModule workflow node uses axios to fetch user-controlled URLs without validating them against the application's internal network blocklist guard (isInternalAddress), bypassing SSRF protections. This issue has been patched in version 4.14.17.
AnalysisAI
Server-side request forgery (SSRF) in FastGPT prior to version 4.14.17 allows authenticated users with App editing privileges to bypass SSRF protections in the lafModule workflow node's fetchData function, enabling arbitrary HTTP requests to internal and private network addresses via unvalidated user-controlled URLs passed to axios without filtering against the application's isInternalAddress blocklist.

Vulnerability AssessmentAI
| Exploitation | The vulnerability requires the attacker to be an authenticated user with App editing privileges to craft or modify a workflow node. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS v4.0 score of 2.3 with vector AV:N/AC:L/AT:P/PR:L indicates network-accessible but low-impact exploitation with attack time penalty (AT:P) and low-privilege requirement (PR:L). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An authenticated user with App editing privileges creates or modifies a workflow that includes a lafModule node with a fetchData function. The attacker configures the node to fetch from a user-controlled URL parameter and sets it to an internal address such as http://169.254.169.254/latest/meta-data (AWS metadata endpoint) or http://localhost:6379 (common Redis port). … |
| Remediation | Upgrade FastGPT to version 4.14.17 or later immediately. … Detailed patch versions, workarounds, and compensating controls in full report. |
