IBM Langflow OSS 1.0.0 through 1.11.2 could allow a remote attacker to obtain sensitive information due to incomplete scrubbing of sensitive credential fields.
AnalysisAI
Unauthenticated remote information disclosure in IBM Langflow OSS 1.0.0 through 1.11.2 allows network-accessible attackers to retrieve sensitive credential fields that are incompletely scrubbed from API responses or workflow data outputs. The CVSS vector (AV:N/AC:L/PR:N/UI:N/C:H) confirms this is exploitable over the network without any authentication or user interaction, and the high confidentiality impact reflects that leaked credentials may include API keys, passwords, or tokens used to integrate with downstream services. …

Vulnerability AssessmentAI
| Exploitation | No special conditions are required beyond network-level access to the Langflow OSS instance - the CVSS vector AV:N/AC:L/PR:N/UI:N/S:U confirms unauthenticated remote exploitation against reachable deployments without requiring any elevated privileges or user interaction. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.5 score is supported by a network-facing, zero-privilege, zero-interaction vector that yields high confidentiality impact - a realistic and defensible rating for unauthenticated credential leakage. … 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 | Patch available per vendor advisory - upgrade IBM Langflow OSS to the fixed version specified in the IBM security advisory at https://www.ibm.com/support/pages/node/7285642; the exact patched version number is not specified in the available input data and should be confirmed directly from that advisory. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify and inventory all Langflow deployments in your environment and verify which versions are deployed against the vulnerable range 1.0.0-1.11.2. …
