The vulnerable section exists in `get_snippet_path(self, path)` lines 155 to 174 in snippets.py. Within the Snippets extension, there exists a `base_path` option but the implementation is vulnerable to Directory Traversal. Additionally, a path relative to a specified, allowed base path can also be used to render the content of a file outside the specified base paths: `-8<- '././././etc/passwd'`. By using the syntax `-8<-'/etc/passwd'` or `-8<-'/proc/self/environ'` the content of these files will be rendered in the generated documentation.

In affected versions an arbitrary file read is possible when using include file syntax. PyMdown Extensions is a set of extensions for the `Python-Markdown` markdown project. This issue is also tracked as GHSL-2023-088. There are no known workarounds for this vulnerability. This issue has been addressed in commit `b8a8f029` and in release version 4.38.2. An attacker targeting such an application may be able to read the files of any Windows user on the host machine and certain system files. The Ombi `documentation` suggests running Ombi as a Service with Administrator privileges. This vulnerability can lead to information disclosure.

In addition, by specifying an absolute path for `arg3`, `Path.Combine` will completely ignore the first two arguments and just return just `arg3`. When using `Path.Combine(arg1, arg2, arg3)`, an attacker may be able to escape to folders/files outside of `Path.Combine(arg1, arg2)` by using '.' in `arg3`. The arbitrary file read vulnerability was present in `ReadLogFile` and `Download` endpoints in `SystemControllers.cs` as the parameter `logFileName` is not sanitized before being combined with the `Logs` directory. Ombi administrators may not always be local system administrators and so this may violate the security expectations of the system. Versions prior to 4.38.2 contain an arbitrary file read vulnerability where an Ombi administrative user may access files available to the Ombi server process on the host operating system. Ombi is an open source application which allows users to request specific media from popular self-hosted streaming servers.
