IBM Langflow OSS 1.0.0 through 1.10.2 could allow a remote authenticated attacker to obtain sensitive information due to a server-side request forgery (SSRF) vulnerability.
AnalysisAI
Server-side request forgery in IBM Langflow OSS 1.0.0 through 1.10.2 allows remote authenticated attackers to force the application server to make outbound HTTP requests to arbitrary destinations, enabling reconnaissance of internal network resources and metadata services. The S:C (scope change) in the CVSS vector confirms the vulnerability can reach internal systems beyond the Langflow application boundary - a hallmark of high-impact SSRF. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid authenticated session on the Langflow instance (PR:L - any low-privileged user account suffices). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 5.0 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N) reflects network-exploitable SSRF with scope change but low confidentiality impact and an authentication prerequisite. … 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 advisory https://www.ibm.com/support/pages/node/7285644 - the advisory should specify the patched release version; upgrade to that version or later. … Detailed patch versions, workarounds, and compensating controls in full report. |
