Kimai: API invoice endpoint missing customer-level access control (IDOR)

Kimai is a web-based multi-user time-tracking application. Prior to version 2.51.0, "GET /api/invoices/{id}" only checks the role-based view_invoice permission but does not verify the requesting user has access to the invoice's customer. Any user with ROLE_TEAMLEAD (which grants view_invoice) can read all invoices in the system, including those belonging to customers assigned to other teams. This issue has been patched in version 2.51.0.

Tuleap allows preview of a linked artifact with a type does not respect permissions

Tuleap is an open source suite to improve management of software developments and collaboration. In Tuleap Community Edition prior to version 14.11.99.28 and Tuleap Enterprise Edition prior to versions 14.10-6 and 14.11-3, the preview of an artifact link with a type does not respect the project, tracker and artifact level permissions. The issue occurs on the artifact view (not reproducible on the artifact modal). Users might get access to information they should not have access to. Only the title, status, assigned to and last update date fields as defined by the semantics are impacted. If those fields have strict permissions (e.g. the title is only visible to a specific user group) those permissions are still enforced. Tuleap Community Edition 14.11.99.28, Tuleap Enterprise Edition 14.10-6, and Tuleap Enterprise Edition 14.11-3 contain a fix for this issue.
