CVE-2021-43805 Information

Description

Solidus is a free open-source ecommerce platform built on Rails. Versions of Solidus prior to 3.1.4 3.0.4 and 2.11.13 have a denial of service vulnerability that could be exploited during a guest checkout. The regular expression used to validate a guest order’s email was subject to exponential backtracking through a fragment like a.a. Versions 3.1.4 3.0.4 and 2.11.13 have been patched to use a different regular expression. The maintainers added a check for email addresses that are no longer valid that will print information about any affected orders that exist. If a prompt upgrade is not an option a workaround is available. It is possible to edit the file config/application.rb manually (with code provided by the maintainers in the GitHub Security Advisory) to check email validity.
