Is this vulnerability remotely exploitable?

Yes. If an attacker has push access to a repository integrated with the project, they can remotely craft malicious filenames. Any user who then views the affected repositories page in their browser can have arbitrary JavaScript executed in their session.

What level of access does an attacker need?

The attacker must be able to push commits to the repository used by the OpenProject project. They generally need write permissions or equivalent access; mere read-only access is not sufficient to introduce the malicious filenames.

What is the safest general fix pattern?

The most robust fix is to ensure all repository-derived text is properly escaped at output time using context-aware HTML encoding, preferably via a templating engine that auto-escapes variables. This should be applied consistently across all views of filenames, paths, and related metadata.
