From 7.1.0 to before 9.9.1, Copier suggests that it&#39;s safe to generate a project from a safe template, i.e. one that doesn&#39;t use unsafe features like custom Jinja extensions which would require passing the --UNSAFE,--trust flag. As it turns out, a safe template can currently write files outside the destination path where a project shall be generated or updated. This is possible when rendering a generated directory structure whose rendered path is either a relative parent path or an absolute path. Constructing such paths is possible using Copier&#39;s builtin pathjoin Jinja filter and its builtin _copier_conf.sep variable, which is the platform-native path separator. This way, a malicious template author can create a template that overwrites arbitrary files (according to the user&#39;s write permissions), e.g., to cause havoc. This vulnerability is fixed in 9.9.1.</p> <p><strong>Affected:</strong> copier-org copier</p> <p>Copier library and CLI app for rendering project templates.
