IBM Langflow OSS 1.0.0 through 1.11.1 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 1.0.0 through 1.11.1 allows an authenticated low-privilege attacker to coerce the application server into issuing arbitrary outbound HTTP requests, enabling internal network enumeration and potentially pivoting to other attacks against backend infrastructure. The CVSS vector (PR:L/AV:N/AC:L) confirms this is exploitable over the network by any authenticated user without elevated permissions or user interaction. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid authenticated session with at least low-privilege access to the Langflow OSS instance (confirmed by CVSS PR:L). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 4.3 (Medium) reflects a real but bounded risk: the network attack vector and low complexity lower the bar for exploitation, but the PR:L requirement limits exposure to authenticated users only. … 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 | Apply the vendor-released patch per IBM's advisory at https://www.ibm.com/support/pages/node/7284579. … Detailed patch versions, workarounds, and compensating controls in full report. |
