NGINX path traversal issue

In the default nginx configuration, those kinds of locations are used with alias directives:

location /_protected/music
location /_protected/media
location /front
location /front/embed.html

Therefore, a request like this could permit to escape the directory: /_protected/media../.. to /path/to/media/../../

To solve this issue, locations to directories should be suffixed with a / and locations to files should be prefixed with = as follows:

location /_protected/music/
location /_protected/media/
location /front/
location =/front/embed.html
