IBM Langflow OSS 1.0.0 through 1.10.3 could allow a remote authenticated attacker to execute arbitrary code due to improper limitation of a pathname to a restricted directory.
AnalysisAI
Path traversal in IBM Langflow OSS (versions 1.0.0 through 1.10.3) enables a remote authenticated attacker to escape restricted directory boundaries and execute arbitrary code on the server. The flaw (CWE-22) is present in IBM's enterprise packaging of the Langflow AI workflow platform and is network-exploitable with low-privilege credentials, yielding full C:H/I:H/A:H impact per CVSS 8.8. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid authenticated session on IBM Langflow OSS with at least low-privilege access (PR:L per CVSS). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.8 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) reflects a high-severity network-exploitable flaw with low complexity and full compromise potential. … 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 | IBM has released a patch for this vulnerability; the primary fix is upgrading IBM Langflow OSS to the version specified in the IBM security advisory at https://www.ibm.com/support/pages/node/7286656 - consult that advisory for the exact patched version number, which is not independently confirmed from the provided data. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: identify all IBM Langflow OSS deployments running versions 1.0.0-1.10.3 and restrict network access to Langflow administrators only. …
