1DescriptionCVE.org
IBM Langflow OSS 1.0.0 through 1.10.2 could allow an authenticated attacker to traverse directories on the system. An attacker could send a specially crafted URL request containing "dot dot" sequences (/../) to view arbitrary files on the system.
AnalysisAI
Path traversal in IBM Langflow OSS versions 1.0.0 through 1.10.2 allows an authenticated low-privileged attacker to read arbitrary files on the underlying server by injecting dot-dot sequences (/../) into crafted URL requests. The CVSS 3.1 score of 6.5 (C:H/I:N/A:N) reflects a read-only disclosure vector with no write or denial-of-service capability, but the confidentiality impact is materially significant given that Langflow deployments commonly store LLM API keys, pipeline configurations, and model secrets on the host filesystem. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid authenticated session with at least low-privilege credentials on the target IBM Langflow OSS instance (PR:L per CVSS vector) - unauthenticated exploitation has not been identified. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N) is well-calibrated: network-exploitable with low complexity, but gated behind a valid authenticated session, and limited to confidentiality loss with no integrity or availability impact. … 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 is available per IBM. … Detailed patch versions, workarounds, and compensating controls in full report. |
Threat intelligence, references, and detailed analysis are available after sign-in.
