AI Analysis
Technical Summary
CVE-2026-67529 describes an information exposure vulnerability in OpenProject before version 17.6.0. The GET /api/v3/time_entries and GET /api/v3/cost_entries endpoints render work package titles and href links without verifying if the user has permission to view the associated work packages. Specifically, the code in time_entry_representer.rb and cost_entry_representer.rb does not check WorkPackage.visible or view_work_packages permissions, allowing users with view_time_entries or view_cost_entries privileges to access private work package subjects and IDs. This issue was addressed and fixed in OpenProject 17.6.0.
Potential Impact
Users with permissions to view time or cost entries can access private information about work packages, including their titles and identifiers, which they should not be authorized to see. This leads to unauthorized disclosure of sensitive project management data. There is no indication of impact on integrity or availability.
Mitigation Recommendations
Upgrade OpenProject to version 17.6.0 or later, where this vulnerability is fixed. No other official remediation or temporary fixes are indicated. Patch status is confirmed by the vendor advisory stating the issue is fixed in 17.6.0.
