What is CVE-2026-109441?

LangAlpha, up to version 2026.09.07, contains an improper isolation vulnerability that allows authenticated users within their own sandbox containers to connect to other tenants' containers. This occurs due to the shared default bridge network in Docker, which enables inter-container communication. As a result, users can bypass security measures designed to restrict access, potentially leading to unauthorized file access, including sensitive data stored in vaults from exposed servers. This vulnerability underscores the importance of isolating multi-tenant environments to protect against unauthorized access and data breaches.
