CVE-2026-13446 identifies a critical vulnerability in IBM Langflow OSS versions 1.0.0 through 1.10.1 where hard-coded credentials such as passwords or cryptographic keys are embedded within the software. These credentials are used for inbound authentication, outbound communication to external components, or encryption of internal data. The presence of hard-coded credentials can allow an attacker to bypass authentication or decrypt sensitive data, leading to full compromise of confidentiality, integrity, and availability. No official patch or remediation level has been published by IBM as of the data provided.

Exploitation of this vulnerability can lead to complete compromise of the affected system, including unauthorized access, data disclosure, data modification, and denial of service. The CVSS score of 9.8 reflects the critical nature of the vulnerability with network attack vector, no required privileges or user interaction, and high impact on confidentiality, integrity, and availability.

Patch status is not yet confirmed — check the IBM vendor advisory for current remediation guidance. Until an official fix is released, users should consider mitigating exposure by restricting network access to the affected components, monitoring for suspicious activity, and preparing for rapid deployment of patches once available.
