IBM Langflow OSS 1.0.0 through 1.11.1 could allow a remote attacker to read arbitrary files due to path traversal.
AnalysisAI
Path traversal in IBM Langflow OSS 1.0.0 through 1.11.1 exposes arbitrary server-side files to unauthenticated remote attackers over the network. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms low-complexity exploitation requiring no credentials or user interaction, with high confidentiality impact limited to file reads - no write or availability impact. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | No special conditions are required - the CVSS vector (AV:N/AC:L/PR:N/UI:N) indicates remote unauthenticated exploitation against IBM Langflow OSS in its default configuration across all versions 1.0.0 through 1.11.1. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 7.5 (High) accurately reflects the attack profile: unauthenticated, network-accessible, low complexity, no user interaction, with high confidentiality 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 | Apply the vendor-released patch referenced in IBM's advisory at https://www.ibm.com/support/pages/node/7284579; the exact patched version number is confirmed available per vendor but is not specified in the available intelligence and must be verified directly from the advisory before deployment. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: audit your infrastructure to identify all Langflow OSS deployments and versions, particularly internet-facing systems; document what sensitive data resides on these servers. …
