# CVE-2026-33733

> 7.2 HIGH · 🧪 PoC

## Beschreibung

EspoCRM is an open source customer relationship management application. Prior to version 9.3.4, the admin template management endpoints accept attacker-controlled `name` and `scope` values and pass them into template path construction without normalization or traversal filtering. As a result, an authenticated admin can use `../` sequences to escape the intended template directory and read, create, overwrite, or delete arbitrary files that resolve to `body.tpl` or `subject.tpl` under the web application user's filesystem permissions. Version 9.3.4 fixes the issue.
