Is this vulnerability remotely exploitable over the internet?

Yes, if the OpenProject instance is exposed and an attacker can obtain an account with permissions to upload attachments to a work package (or similar container) that can be exported to PDF. The exploitation itself is triggered when the server processes the PDF export.

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

The attacker needs authenticated access with the ability to upload attachments to at least one entity that supports PDF export. No direct shell or filesystem access is required; the attack is carried out entirely via the web interface and backend processing.

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

The most robust pattern is to strictly control how untrusted files are handled: enforce strong file-type validation, configure external processors like ImageMagick with restrictive security policies, and avoid letting untrusted content drive powerful interpreters or coders that can reach local files.
