CVE-2026-116492 · Severity: medium · CVSS 6.5 · Published 2026-10-26

Frappe CRM contains an authorization flaw in its phone number lookup API that allows low-privileged users to retrieve sensitive customer lead information they should not have access to. An attacker with basic user credentials can query lead details by phone number, bypassing access controls and exposing confidential CRM data such as contact names and company information.

Technical details

The get_contact_by_phone_number API endpoint performs raw database queries without invoking the permission system, allowing authenticated low-privileged users to bypass CRM access controls. An attacker supplies a known phone number to retrieve full lead details that are otherwise blocked by standard API and UI access controls. The vulnerability was fixed in version 1.89.1 by splitting phone lookup logic to use separate server-side helpers with proper authorization.
