{"id":"CVE-2025-63800","details":"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.","modified":"2026-08-12T03:51:18.665313137Z","published":"2025-11-18T00:00:00Z","database_specific":{"cna_assigner":"mitre","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/63xxx/CVE-2025-63800.json"},"references":[{"type":"WEB","url":"https://github.com/omkaryepre/vulnerability-research/tree/main/CVE-2025-63800"},{"type":"WEB","url":"https://opensourcepos.org/"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/63xxx/CVE-2025-63800.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-63800"},{"type":"PACKAGE","url":"https://github.com/opensourcepos/opensourcepos"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/opensourcepos/opensourcepos","events":[{"introduced":"5f395d987b02562092b838073cb2e23a22d2bca4"},{"last_affected":"5f395d987b02562092b838073cb2e23a22d2bca4"}],"database_specific":{"extracted_events":[{"introduced":"3.4.1"},{"last_affected":"3.4.1"}],"source":"CPE_STRING","cpe":"cpe:2.3:a:opensourcepos:open_source_point_of_sale:3.4.1:*:*:*:*:*:*:*"}}],"versions":["3.4.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-63800.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
