AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Network-reachable service, low complexity, requires a low-privilege authenticated account to author code-bearing flows (PR:L); resulting RCE on the host gives total C/I/A impact.

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 generation of code.
AnalysisAI
Remote code execution in IBM Langflow OSS versions 1.0.0 through 1.12.2 allows an authenticated attacker with flow-authoring privileges to inject and execute arbitrary code through Langflow's code-generation mechanism (CWE-94). The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) rates this as high severity (8.8), requiring network reachability, low privileges, and no user interaction; however, in typical deployments where flow creation or modification is broadly granted, the practical barrier may be lower than the PR:L metric implies. …

Vulnerability AssessmentAI
| Exploitation | Requires an authenticated session with sufficient privilege to create or modify flows/components in Langflow OSS, which is the mechanism through which code generation is controlled (CWE-94). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals are moderate and largely consistent. … 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: IBM has published a patch (exact fixed version not provided in the CVE data); consult the IBM advisory at https://www.ibm.com/support/pages/node/7290694 for the patched release and upgrade instructions. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all IBM Langflow OSS deployments, confirm affected versions (1.0.0 through 1.12.2), and restrict flow-authoring privileges to only essential personnel; audit for any suspicious flow modifications. …
