Routine
HIGH 7.6
CVE-2026-67527 is a high-severity flaw (CVSS 7.6) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
OpenProject is open-source, web-based project management software. Prior to 17.6.0, PATCH /api/v3/work_packages/{id} accepted _links.fileLinks and allowed authenticated users with edit_work_packages but without manage_file_links to resolve Storages::FileLink records by raw id, detach or hard-delete existing FileLinks, and re-parent FileLinks from other projects to an attacker-controlled work package, exposing origin filename, origin id, and MIME
Why this priority
- High severity
No fix is published yet: follow the downgrade or mitigation steps.
