# CordysCRM: authenticated users can read other users' customer contacts

Link for people: https://infrastack.ai/live/CVE-2026-126496 (this .md is for agents)

CordysCRM before 1.9.6 has an authorization bypass in the contact lookup endpoint, so any logged-in user with contact read permission can fetch another user's contact by ID. The exposed data includes names, phone numbers, owners, departments, linked customers and custom fields.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the CordysCRM version in use; versions below `1.9.6` are in the affected range.
- Review whether ordinary users hold contact or customer read permission on your instance.

## Fix

- CordysCRM: upgrade to `1.9.6` or later (the sources state the fix is in `1.9.6`).

- [fix] Release notes: github.com https://github.com/1Panel-dev/CordysCRM/releases/tag/v1.9.6

## From the sources

1Panel-dev CordysCRM before 1.9.6 contains an authorization bypass vulnerability in CustomerContactController.get that allows authenticated users to read other users' contacts because no organization, owner or data-scope check is applied. Attackers holding ordinary contact or customer read permission can request GET /account/contact/get/{id} with another contact's ID to obtain names, phone numbers, owners, departments, linked customers and custom fields.
