## Overview

Frappe Framework before 15.120.0 and 16.x before 16.33.0 does not enforce the per-user restrict_ip allowlist for non-session authentication methods, including API key, OAuth, and header-based authentication. Attackers holding valid credentials of these types can authenticate from IP addresses outside the allowlist, defeating the configured network-based access restrictions.

## Affected

- `frappe >= 16.0.0 < 16.33.0`
- `frappe < 15.120.0`

## Remediation
