Description

Dolibarr before 24.0.0 contains an improper authorization vulnerability in the user REST API update endpoint that allows attackers with user-write rights to modify payroll fields by exploiting an incomplete credential denylist that omits payroll columns. Attackers can rewrite salary, bonus, hourly rate, daily rate, and weekly hours for any user without holding payroll rights, with the modified values appearing in payroll export reports.
