What is CVE-2023-40274?
CVE-2023-40274 is a high-severity path traversal vulnerability in n/a, published on 14 Aug 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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.
Weakness: CWE-22
