Description Carlos López 2023-08-14 08:20:01 UTC 
CVE-2023-40274

An issue was discovered in zola 0.13.0 through 0.17.2. The custom implementation
of a web server, available via the "zola serve" command, allows directory
traversal. The handle_request function, used by the server to process HTTP
requests, does not account for sequences of special path control characters
(../) in the URL when serving a file, which allows one to escape the webroot of
the server and read arbitrary files from the filesystem.

Not sure if the PR really did fix things. I just applied it as a patch. Feel free to change it to RESOLVED [FIXED] once confirmed :D
