CVE-2026-24686— go-tuf 路径遍历漏洞

go-tuf Path Traversal in TAP 4 Multirepo Client Allows Arbitrary File Write via Malicious Repository Names

go-tuf is a Go implementation of The Update Framework (TUF). go-tuf's TAP 4 Multirepo Client uses the map file repository name string (`repoName`) as a filesystem path component when selecting the local metadata cache directory. Starting in version 2.0.0 and prior to version 2.4.1, if an application accepts a map file from an untrusted source, an attacker can supply a `repoName` containing traversal (e.g., `../escaped-repo`) and cause go-tuf to create directories and write the root metadata file outside the intended `LocalMetadataDir` cache base, within the running process's filesystem permissions. Version 2.4.1 contains a patch.

对路径名的限制不恰当(路径遍历)

go-tuf 路径遍历漏洞

go-tuf是The Update Framework开源的一个用于保护软件更新系统的框架。 go-tuf 2.0.0至2.4.1之前版本存在路径遍历漏洞，该漏洞源于使用存储库名称字符串作为文件系统路径组件时存在路径遍历，可能导致在预期缓存目录外创建目录和写入文件。
