Description
Frappe HR (hrms) before 16.11.0, including all 14.x and 15.x releases through 15.64.3, contains a missing authorization vulnerability in the whitelisted expire_allocation method that allows authenticated users to expire any leave allocation. Attackers without HR roles can name another employee's Leave Allocation in a POST request to zero its allocated leaves and wipe that employee's remaining leave balance.
