CVE-2026-108733
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.
Does this matter?
Lower severity and a low EPSS score (0.26%). Track it; it rarely justifies an emergency change on its own.
Description
