CVE-2026-9103 Details
Description
IBM Langflow OSS 1.0.0 through 1.10.0 could allow a remote attacker to gain unauthorized access due to improper authentication in the /api/v1/login/auto_login endpoint. The endpoint issues long-lived superuser bearer tokens without requiring authentication when the AUTO_LOGIN configuration is enabled (enabled by default), which may allow an unauthenticated network attacker to obtain full administrative access. Additionally, permissive cross-origin resource sharing (CORS) settings may allow tokens to be exposed to unintended origins, increasing the risk of unauthorized access.
A vulnerability in IBM Langflow OSS versions 1.0.0 through 1.10.0 allows remote attackers to gain unauthorized access via the /api/v1/login/auto_login endpoint. This endpoint, when the AUTO_LOGIN configuration is enabled (which is the default), issues long-lived superuser bearer tokens without requiring authentication. As a result, an unauthenticated network attacker could obtain full administrative access. Additionally, the application's permissive cross-origin resource sharing (CORS) settings may expose these tokens to unintended origins, further increasing the risk of unauthorized access.
Users are advised to upgrade IBM Langflow OSS to version 1.10.1.
