5DescriptionCVE.org
A vulnerability was found in FlowiseAI Flowise up to 3.0.2. This vulnerability affects the function axios.post of the file packages/server/src/controllers/evaluations/index.ts of the component Evaluations Endpoint. The manipulation of the argument Host/X-Forwarded-Proto results in server-side request forgery. The attack may be launched remotely. The exploit has been made public and could be used. Upgrading to version 3.1.3 is able to resolve this issue. The patch is identified as 700137738bcaebefd4709021f6d6b0abcd7df0ac. It is recommended to upgrade the affected component. This vulnerability only affects products that are no longer supported by the maintainer.
AnalysisAI
Server-side request forgery in FlowiseAI Flowise up to version 3.0.2 allows authenticated users to redirect internal server-side HTTP requests by supplying attacker-controlled Host and X-Forwarded-Proto headers to the Evaluations endpoint, causing the server to construct the axios.post base URL from untrusted input rather than a trusted server-side value. The flaw enables the Flowise server to be leveraged as a proxy for reaching internal network resources, cloud metadata services, or adjacent microservices invisible to the external attacker. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid authenticated session with low-privilege access to the Flowise application (CVSS PR:L confirmed by the CVSS 4.0 vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P, score 5.3) accurately reflects the core risk profile: network-reachable, low complexity, low-privilege SSRF with limited per-impact ratings and a confirmed public exploit modifier. … 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 | Upgrade FlowiseAI Flowise to version 3.1.3 or later, which replaces attacker-controlled header-derived URL construction with the server-side APP_URL environment variable (patch commit 700137738bcaebefd4709021f6d6b0abcd7df0ac, official release at https://github.com/FlowiseAI/Flowise/releases/tag/flowise%403.1.3). … Detailed patch versions, workarounds, and compensating controls in full report. |
