CVE-2026-77817 · Severity: medium · CVSS 6.5 · Published 2026-10-29

IBM Langflow OSS is a low-code platform for building AI applications. When users export flows or projects, sensitive credentials and secrets are not properly masked or removed from the exported files, allowing authenticated users to view this confidential information. An attacker with access to exported files could obtain API keys, passwords, and other secrets used by the application.

## Technical details

IBM Langflow OSS fails to sanitize secrets during flow and project export operations, exposing sensitive credentials to authenticated users. The vulnerability affects versions 1.0.0 through 1.12.4 and requires user authentication to exploit. An attacker can export workflows containing stored secrets and retrieve them in plaintext, bypassing the intended protection of credential storage.

## Affected products

- IBM Langflow OSS 1.0.0 through 1.12.4
