Is this vulnerability remotely exploitable over the internet?

Yes, if OpenProject is exposed over the network, any authenticated user with the `:browse_repository` permission on a project can trigger the vulnerability by sending crafted HTTP requests to the repository diff download endpoint.

What level of access does an attacker need to exploit this issue?

The attacker must be able to log into OpenProject (or otherwise obtain valid session credentials) and have `:browse_repository` permission for the target project. No shell access to the server is required; exploitation is performed via the web interface.

What is the safest general fix pattern for this class of issue?

The most reliable fix is to ensure that untrusted input is never allowed to alter command options. Validate revision identifiers against strict patterns, reject or normalize values that resemble flags, and invoke Git using APIs or helper functions that construct fixed command templates with user input restricted to safe, positional arguments.
