Version 3.2.0

Version 3.2.0 resolved an issue where a specially crafted request could result in a DNS query to an arbitrary domain.

This issue was found by Cyber Smart Defence who reported it as part of a security audit to a firm running a local installation of Read the Docs.

Release 2.3.0

Version 2.3.0 resolves a security issue with translations on our community hosting site that allowed users to modify the hosted path of a target project by adding it as a translation project of their own project. A check was added to ensure project ownership before adding the project as a translation.

In order to add a project as a translation now, users must now first be granted ownership in the translation project.
