AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
Network-reachable, low-complexity information disclosure needing a low-privilege account (PR:L); scope change (S:C) because data crosses to an unauthorized actor; confidentiality-only impact (C:H, I/A:N).

IBM Langflow OSS 1.0.0 through 1.12.2 could allow a remote authenticated attacker to obtain sensitive information due to exposure of sensitive information to an unauthorized actor.
AnalysisAI
Information disclosure in IBM Langflow OSS 1.0.0 through 1.12.2 allows a remote, authenticated attacker holding only low-privilege credentials to obtain sensitive information that should not be reachable from their account, resulting in a high confidentiality impact with no effect on integrity or availability. The CVSS vector (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N) confirms credentials are required and that no user interaction is needed, while the scope-change metric indicates the exposed data can affect resources beyond the vulnerable component itself. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated session with at least low-privilege access to an IBM Langflow OSS instance running an affected version (1.0.0 through 1.12.2); the CVSS PR:L confirms credentials are needed, so unauthenticated internet scanning alone cannot trigger it. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a credible mid-tier priority rather than an emergency. … 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 | The primary fix is to apply the vendor patch identified in IBM's advisory at https://www.ibm.com/support/pages/node/7290694, which lists the remediated Langflow OSS level; only the advisory confirms the exact fixed build, so upgrade to the version specified there rather than assuming any release above 1.12.2 is automatically covered, and re-verify the installed version after upgrade since the CPE range is wildcarded. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all IBM Langflow OSS instances and confirm which are running versions 1.0.0 through 1.12.2; apply the vendor-released patch per the vendor advisory immediately, and if patching cannot be completed, restrict network access to trusted users only. …
