AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Network-reachable (AV:N), low complexity (AC:L), requires a low-privileged authenticated account (PR:L), no user interaction; code injection yields full host compromise, so C/I/A all High.

IBM Langflow OSS 1.0.0 through 1.12.2 could allow a remote authenticated attacker to execute arbitrary code due to improper control of code generation.
AnalysisAI
Authenticated remote code execution in IBM Langflow OSS 1.0.0 through 1.12.2 allows a low-privileged user to run arbitrary code because the platform improperly controls generation of executable code (CWE-94). Exploitation requires only a valid account on the instance (CVSS PR:L, AV:N, AC:L, UI:N), so an attacker who holds or obtains any credential able to create, import, or execute a flow/component that reaches the vulnerable code-generation path can achieve full confidentiality, integrity, and availability impact on the host. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid authenticated account on the Langflow OSS instance (CVSS PR:L) with the ability to create, import, or execute a flow/component that reaches the vulnerable code-generation path (CWE-94). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuinely serious but not emergency-tier vulnerability. … 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 patch: IBM has published remediation on the support page linked from the CVE (https://www.ibm.com/support/pages/node/7290694) and patch availability is confirmed, so upgrade Langflow OSS to the fixed release identified in that advisory - no exact fixed version number is stated in the provided data, so consult the IBM page rather than assuming a specific version; any release at or below 1.12.2 remains exposed. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all IBM Langflow OSS instances and identify any running versions 1.0.0 through 1.12.2; restrict network access to trusted administrative networks, enforce least privilege on Langflow accounts, and review authentication and flow-execution logs for anomalous activity. …
