CVE-2026-67529

Description

OpenProject is open-source, web-based project management software. Prior to 17.6.0, GET /api/v3/time_entries and GET /api/v3/cost_entries rendered _links.workPackage.title and _links.workPackage.href through associated_resource in modules/costs/lib/api/v3/time_entries/time_entry_representer.rb and modules/costs/lib/api/v3/cost_entries/cost_entry_representer.rb without checking WorkPackage.visible or view_work_packages, allowing users with view_time_entries or view_cost_entries to read private work package subjects and ids. This issue is fixed in 17.6.0.
