Quick assessment

Affected
flightphp core
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Flight是Mike Cao个人开发者的一个PHP微框架。 Flight 3.18.1之前版本存在路径遍历漏洞，该漏洞源于make:controller CLI命令在类名验证前，基于用户提供的控制器名称创建目录，可能导致通过../遍历在项目根目录外创建目录。

Vulnerability Title
Flight: Path traversal in `make:controller` CLI creates arbitrary directories outside project root
Source: CVE Program / CVE List V5
Vulnerability Description
Flight is an extensible micro-framework for PHP. Prior to 3.18.1, the make:controller CLI command calls mkdir(..., recursive: true) on a path built from the user-supplied controller name, before Nette's class-name validation runs. The class-file write is correctly rejected by Nette when the name contains /, but the recursive directory creation side effect is already committed — including directories located outside the project root through ../ traversal. This vulnerability is fixed in 3.18.1.
