Vulnerability Title
Claude Desktop: SSH Host Key Verification Bypass Allows Man-in-the-Middle Attack on Remote Sessions
Vulnerability Description
The Claude Desktop app gives you Claude Code with a graphical interface built for running multiple sessions side by side. From 1.2581.0 to before 1.4304.0, Claude Desktop's SSH remote development feature verified only whether a hostname existed in ~/.ssh/known_hosts without comparing the server's presented host key against the stored key. This allowed a network-positioned attacker to present an arbitrary SSH host key and have the connection silently accepted, enabling a man-in-the-middle attack on remote development sessions. Successful exploitation required the attacker to be in a network position to intercept SSH traffic (e.g., via ARP spoofing, rogue Wi-Fi, or DNS poisoning) and the target hostname to already have an entry in the victim's known_hosts file. This vulnerability is fixed in 1.4304.0.

Vulnerability Title
Claude Code 安全漏洞
Vulnerability Description
Claude Code是Anthropic开源的一个终端原生AI编程工具。 Claude Code 1.2581.0至1.4304.0之前版本存在安全漏洞,该漏洞源于SSH远程开发功能仅验证主机名是否存在于known_hosts文件中而未比较服务器呈现的主机密钥,可能导致网络位置的攻击者呈现任意SSH主机密钥并静默接受连接,从而对远程开发会话进行中间人攻击。
