As an impact it is known to affect confidentiality. CVE summarizes:

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.

The weakness was disclosed 08/14/2023 as 2257. The advisory is shared for download at github.com. This vulnerability was named CVE-2023-40274 since 08/14/2023. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1006.
