description

IBM Langflow OSS 1.0.0 through 1.12.2 does not adequately confine file operations initiated by authenticated flow authors. A permitted author may write files where the service account has access and obtain files readable by that account, potentially exposing application data or secrets.

mitigation

Upgrade Langflow OSS to 1.12.3 or later; use 1.12.5 where possible for the recommended patch set. Until upgraded, restrict flow-author access and limit the service account's filesystem permissions.
