CVE-2026-116492
Frappe CRM before 1.89.1 Missing Authorization via Phone Lookup API
Description
Frappe CRM app before 1.89.1 contains a missing authorization vulnerability that allows authenticated low-privileged users to read CRM Lead records they are not permitted to access by querying the get_contact_by_phone_number API, which performs raw database queries without invoking the permission system. Attackers can supply a known phone number to the crm.integrations.api.get_contact_by_phone_number endpoint to retrieve full lead details otherwise blocked by standard API and UI access controls, resulting in unauthorized disclosure of sensitive CRM data.
