Quick assessment

Affected
ginlix-ai LangAlpha
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

LangAlpha 在 2026 年 9 月 7 日及之前的版本中存在间接提示注入漏洞。该漏洞允许远程攻击者通过在代理获取的网页内容中植入指令，从而执行 Shell 命令或 Python 代码。由于 Bash 和 ExecuteCode 工具缺乏白名单机制以及“人工介入”（human-in-the-loop）的审批流程，攻击者能够在工作区沙箱中运行代码，并从 文件中窃取保险库（vault）中的秘密信息。

Vulnerability Title
LangAlpha through 2026.09.07 Indirect Prompt Injection RCE via Bash and ExecuteCode
Source: CVE Program / CVE List V5
Vulnerability Description
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.
