LangAlpha through 2026.09.07 Indirect Prompt Injection RCE via Bash and ExecuteCode

Assigner: VulnCheck
Reserved: 12.10.2026 Published: 20.10.2026 Updated: 20.10.2026

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.
