IBM Langflow OSS 1.0.0 through 1.11.2 is vulnerable to server-side request forgery (SSRF). This may allow an authenticated attacker to send unauthorized requests from the system, potentially leading to network enumeration or facilitating other attacks.
AnalysisAI
Server-side request forgery in IBM Langflow OSS versions 1.0.0 through 1.11.2 allows authenticated network attackers to induce the server to issue unauthorized HTTP requests to arbitrary destinations, enabling internal network enumeration or use of the server as a proxy to reach otherwise-isolated services. The vulnerability is classified as CWE-918 and is confirmed by IBM with a patch available at the vendor support page. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid authenticated user account on the Langflow OSS instance (PR:L per CVSS). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 5.4 Medium score accurately reflects a constrained but real exposure: network-reachable, low complexity, but gated behind authenticated access (PR:L), which meaningfully limits the attacker population to registered or compromised users. … 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 | Vendor-released patch is available per IBM's advisory at https://www.ibm.com/support/pages/node/7285639; administrators should consult that page for the exact fixed version and apply the upgrade immediately. … Detailed patch versions, workarounds, and compensating controls in full report. |
