Summary

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. An authenticated user with code execution in their own sandbox can connect directly to other tenants' containers, bypassing require_workspace_owner checks.

Risk Assessment

A tenant can access other tenants' data and secrets, violating isolation boundaries and confidentiality. This may lead to theft of secrets from exposed servers.

Recommendation

Upgrade LangAlpha to a version later than 2026.09.07 that fixes sandbox network isolation. Until then, disable inter-container communication and restrict code execution in sandboxes.

Other vulnerabilities in LangAlpha

CVE-2026-109440High
LangAlpha through 2026.09.07 contains an indirect prompt injection vulnerability that allows remote attackers to execute shell commands or Python by planting instructions in web content retrieved by the agent. Because Bash and ExecuteCode lack an allow-list and human-in-the-loop approval, attackers can run code in the workspace sandbox and exfiltrate vault secrets from _internal/.vault_secrets.json.

Original NVD description (English source)

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.
