Path Traversal occurrences in Wp All Import
The Import any XML or CSV File to WordPress plugin before 3.6.9 is not validating the paths of files contained in uploaded zip archives, allowing highly privileged users, such as admins, to write arbitrary files to any part of the file system accessible by the web server via a path traversal vector. (2022-11-07, CVE-2022-2711)
Why Path Traversal can be dangerous
Relative Path Confusion means that your web server is configured to serve responses to ambiguous URLs. This configuration can possibly cause confusion about the correct relative path for the URL. It is also an issue of resources, such as images, styles etc., which are specified in the response using relative path, not the absolute URL.
If the web browser permits to parse "cross-content" response, the attacker may be able to fool the web browser into interpreting HTML into other content types, which can then lead to a cross site scripting attack (link do XSS).
