### Official description

A weakness has been identified in TiBillet Lespass up to 10e87909c5d526dffa6d424c104fc12860740537. This vulnerability affects the function get_img_from_url of the file ApiBillet/serializers.py of the component APIv1. Executing a manipulation of the argument img_url/image_url can lead to server-side request forgery. The attack can be launched remotely. A high complexity level is associated with this attack. It is stated that the exploitability is difficult. The vendor confirms: "[T]he fix (destination IP validation, redirect re-checks, timeout and size limit on remote image download) is already planned in our v2 API, which replaces the affected v1 endpoints. The v1 API, including the three affected serializers, will be removed in our next major release."
