goshs has a file-based ACL authorization bypass in goshs state-changing routes

goshs is a SimpleHTTPServer written in Go. Prior to 2.0.0-beta.4, goshs enforces the documented per-folder .goshs ACL/basic-auth mechanism for directory listings and file reads, but it does not enforce the same authorization checks for state-changing routes. An unauthenticated attacker can upload files with PUT, upload files with multipart POST /upload, create directories with ?mkdir, and delete files with ?delete inside a .goshs-protected directory. By deleting the .goshs file itself, the attacker can remove the folder's auth policy and then access previously protected content without credentials. This results in a critical authorization bypass affecting confidentiality, integrity, and availability. This vulnerability is fixed in 2.0.0-beta.4.

授权机制缺失

goshs 安全漏洞

goshs是Patrick Hener个人开发者的一个用Go编写的简单HTTP Server。 goshs 2.0.0-beta.4之前版本存在安全漏洞，该漏洞源于未对状态更改路由强制执行相同的授权检查，可能导致未经身份验证的攻击者在受.goshs保护的目录内上传、创建目录、删除文件，并通过删除.goshs文件本身移除文件夹的认证策略，从而绕过授权。
