CVE-2026-58403— GoHugo Hugo 后置链接漏洞

Hugo symlink confinement bypass in os.ReadFile

Hugo is a static site generator. From v0.123.0 through v0.163.0, Hugo's virtual filesystem is designed so that files under a mount cannot reach outside the mount tree, but a regression caused RootMappingFs.statRoot to call Stat, which follows symlinks, instead of Lstat, so a direct os.ReadFile "somefile" where somefile was a symlink pointing outside the mount would return the target's contents. This effectively let a symlink planted inside a theme or local mount read arbitrary files reachable to the user running hugo. This issue is fixed in v0.163.1.

在文件访问前对链接解析不恰当(链接跟随)

GoHugo Hugo 后置链接漏洞

gohugo hugo是gohugo团队开源的一个生成静态网站的框架。 GoHugo Hugo v0.123.0版本至v0.163.0版本存在后置链接漏洞，该漏洞源于文件系统回归导致RootMappingFs.statRoot调用Stat而非Lstat，使得符号链接指向挂载树外文件时可读取任意文件，可能导致任意文件读取。
