Vulnerability Title
nanobot: Path traversal via unsanitized WhatsApp document fileName enables arbitrary file write
Vulnerability Description
nanobot is a personal AI assistant. In versions 0.1.5.post3 and prior, the WhatsApp bridge in bridge/src/whatsapp.ts constructs a filesystem path using the fileName field from an incoming WhatsApp document message without sanitization. The WhatsApp bridge downloads media attachments and writes them to disk using a filename derived from the sender's message via documentMessage.fileName, which is concatenated with a prefix and its raw value is passed directly to path.join(mediaDir, outFilename). Node.js path.join resolves .. components, allowing an attacker to escape the intended media/ directory by sending a document with a crafted fileName such as ../../../.ssh/authorized_keys. Because the attacker also controls the file content (the downloaded buffer), this is a write-anywhere primitive — both path and content are attacker-controlled. A fix for this issue is planned for version 0.1.5.post4.

对路径名的限制不恰当(路径遍历)
Vulnerability Title
HKUDS nanobot 路径遍历漏洞
Vulnerability Description
HKUDS nanobot是HKUDS的嵌入式Web服务器。 HKUDS nanobot 0.1.5.post3及之前版本存在路径遍历漏洞,该漏洞源于WhatsApp桥接器在构建文件系统路径时未对fileName字段进行清理,可能导致攻击者通过特制的文件名写入任意文件。
