Since the vulnerability requires authentication, restricting access to trusted users and monitoring export activities may reduce risk. Check IBM's official advisories for updates or patches addressing this issue.
Description
IBM Langflow OSS versions 1.0.0 through 1.12.4 contain a vulnerability where a remote authenticated attacker can obtain sensitive information due to improper sanitization of secrets during flow and project exports. This exposure of sensitive data does not affect integrity or availability but impacts confidentiality.
