CVE-2025-63800

7.5 highEPSS 0.5%

High (7.5) in opensourcepos open source point of sale. EPSS 0.5% chance of exploitation in the next 30 days.

The password change endpoint in Open Source Point of Sale 3.4.1 allows users to set their account password to an empty string due to missing server-side validation. When an authenticated user omits or leaves the `password` and `repeat_password` parameters empty in the password change request, the backend still returns a successful response and sets the password to an empty string. This effectively disables authentication and may allow unauthorized access to user or administrative accounts.
