TL;DR

The REST API timesheet collection endpoint does not enforce activity-team access controls when listing timesheets. The permission criteria applied to the collection query validates only project and customer team permissions. A user with permission to view other timesheets can list entries tied to activities restricted to teams they do not belong to, even though the single-entity endpoint correctly denies access. The fix extends the query filtering to include activity-team restrictions.

Who does this affect?

You are affected if you are using a version that falls within the vulnerable range and you grant users permission to view other users' timesheets while relying on activity-team restrictions.
