Description
LangAlpha through 2026.09.07 contains an improper isolation vulnerability that places all tenants' sandbox containers on Docker's shared default bridge network with inter-container communication enabled. Authenticated users with code execution in their own sandbox can connect directly to other tenants' containers, bypassing require_workspace_owner checks to read files such as vault secrets from exposed servers.
