Vulnerability Title
h3 before 1.15.9 Path Traversal via Double Decoding
Vulnerability Description
h3 versions before 1.15.9 contain a path traversal vulnerability in the serveStatic utility. A double-decoding flaw allows a request path containing double-encoded dot sequences (e.g. %252e%252e) to be decoded to %2e%2e, which survives resolveDotSegments() because that function only checks for literal '.' characters. When the resulting asset ID is resolved by URL-based backends (CDN, S3, object storage), %2e%2e is interpreted as '..' per RFC 3986, enabling path traversal to read arbitrary files from the backend.

Vulnerability Type
对路径名的限制不恰当(路径遍历)
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 1.15.9之前版本存在路径遍历漏洞,该漏洞源于serveStatic工具的双重解码缺陷,请求路径中的双重编码点序列(如%252e%252e)被解码为%2e%2e,绕过resolveDotSegments()函数仅检查字面“.”字符的限制,当结果资产ID由基于URL的后端(CDN、S3、对象存储)解析时,%2e%2e按RFC 3986被解释为“..”,导致路径遍历,从而读取后端任意文件。
