Vulnerability Title
h3 before 1.15.6 Path Traversal via Percent-Encoded Dot Segments
Vulnerability Description
h3 (npm package) versions <= 2.0.1-rc.14 contain a path traversal vulnerability in serveStatic(). On Node.js deployments, event.url.pathname is not normalized, so percent-encoded dot segments (%2e%2e) are passed to decodeURI() and decoded to ../ sequences without sanitization. An unauthenticated remote attacker can send crafted requests to endpoints served by serveStatic() to read arbitrary files outside the intended static directory. Fixed in 1.15.6 and 2.0.1-rc.15.

Vulnerability Title
H3 路径遍历漏洞
Vulnerability Description
H3是H3组织开源的一个HTTP框架。 H3 2.0.1-rc.14及之前版本存在路径遍历漏洞,该漏洞源于serveStatic()函数未对event.url.pathname进行规范化,导致百分号编码的点段(%2e%2e)经decodeURI()解码为../序列后未进行清理,未经身份验证的远程攻击者可通过发送特制请求读取静态目录之外的任意文件。
