Background
tryton-server is a package in the Debian ecosystem that provides a server for the Tryton application framework. Tryton is a three-tier high-level general-purpose application platform that is used to build business applications. The tryton-server package is responsible for handling various server-side functionalities of Tryton. However, a security vulnerability has been discovered in tryton-server that allows an attacker to open files outside the root directory of trytond by using a forged Report name.
