Severity by source
AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Network-accessible code injection requiring only a low-privilege account yields full system compromise; scope unchanged as exploitation does not cross security boundaries beyond the application process.

IBM Langflow OSS 1.0.0 through 1.11.1 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 1.0.0 through 1.11.1 allows a network-accessible authenticated attacker with low privileges to inject and execute arbitrary code server-side due to improper control of code generation (CWE-94). The CVSS 8.8 High score reflects low attack complexity, no required user interaction, and full confidentiality, integrity, and availability impact against the vulnerable host. …

Vulnerability AssessmentAI
| Exploitation | The CVSS vector confirms a valid low-privilege authenticated account on the IBM Langflow OSS instance is required (PR:L) - unauthenticated exploitation is not supported by available data. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.8 High rating is well-supported: the network attack vector (AV:N), low complexity (AC:L), and absence of user interaction (UI:N) mean exploitation is straightforward for any authenticated attacker. … 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 the IBM advisory at https://www.ibm.com/support/pages/node/7284733; consult that page directly for the confirmed fixed version number, as it was not specified in available data. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
