Technical details

A path traversal vulnerability exists in the `trestle author jinja` command within `trestle/core/commands/author/jinja.py`. The `-o/--output` argument fails to properly validate user-supplied paths, including absolute paths and traversal sequences like `../` or `..\`. An attacker can exploit this to write files outside the intended workspace, potentially overwriting sensitive files such as GitHub Actions workflows (`.github/workflows/*.yml`), Git hooks, or shell configuration files (`.bashrc`). This can be achieved with local access and no authentication, running with the privileges of the user executing the command. The issue is fixed in versions 3.12.2 and 4.0.3.

Affected products

oscal-compass compliance-trestle >= 4.0.0, < 4.0.3; <= 3.12.1
