Impact
A malicious actor could read sensitive files from the environment where TechDocs documentation is built and published by setting a particular path for docs_dir in mkdocs.yml. These files would then be available over the TechDocs backend API.
This vulnerability is mitigated by the fact that an attacker would need access to modify the mkdocs.yml in the documentation source code, and would also need access to the TechDocs backend API.
Patches
