IBM Langflow OSS 1.0.0 through 1.12.2 could allow a remote authenticated attacker to obtain sensitive information due to improper limitation of a pathname to a restricted directory.
AnalysisAI
Authenticated path traversal in IBM Langflow OSS 1.0.0 through 1.12.2 lets a remote attacker who already holds a valid low-privilege account or session reach files outside the intended restricted directory, exposing sensitive information hosted on or reachable from the Langflow instance (CWE-22). The flaw is network-reachable with low attack complexity and no user interaction required, but it is explicitly not unauthenticated - an attacker must first be able to log in, so internet-exposed deployments with self-service registration or shared credentials carry the greatest realistic risk. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to already hold valid authenticated access to the Langflow OSS instance (CVSS PR:L), so an account or valid session is the primary prerequisite - this is not an unauthenticated flaw. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The input CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N) describes a network-reachable, low-complexity path traversal (CWE-22) requiring only low-privilege authentication (PR:L), which supports a genuinely elevated risk rating for any internet-exposed Langflow instance. … 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 status is "Patch available per vendor advisory": IBM has released a fix and documents it at https://www.ibm.com/support/pages/node/7290694, which should be consulted for the exact patched version - upgrade any Langflow OSS instance running 1.0.0 through 1.12.2 to the fixed release named in that advisory (no specific fixed version number is provided in the available data, so it should be read directly from the IBM page rather than assumed). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all deployments of IBM Langflow OSS versions 1.0.0 through 1.12.2 and restrict network access to trusted users only. …
