95-99: Excellent security improvement to prevent XSS vulnerabilities.This change properly addresses the security issue by enabling autoescaping for HTML and XML templates. Using the
Environmentwithselect_autoescapeis the recommended approach to mitigate XSS risks.There's a slight inconsistency in the implementation: you're setting up a
FileSystemLoaderbut still usingfrom_string()instead of loading the template from a file. Consider refactoring to be more consistent:-template_content = settings.input_template_file.read_text("utf-8") -env = Environment( - loader=FileSystemLoader(searchpath=str(settings.input_template_file.parent)), - autoescape=select_autoescape(['html', 'xml']) -) -template = env.from_string(template_content) +env = Environment( + loader=FileSystemLoader(searchpath=str(settings.input_template_file.parent)), + autoescape=select_autoescape(['html', 'xml']) +) +template = env.get_template(settings.input_template_file.name)This would utilize the
FileSystemLoaderproperly while maintaining the same functionality.

10-10: Import statement update looks good.The update from
from jinja2 import Templatetofrom jinja2 import Environment, FileSystemLoader, select_autoescapecorrectly imports the necessary components for implementing the secure template environment.

Potential fix for https://github.com/khulnasoft/latest-changes/security/code-scanning/2
To fix the problem, we need to ensure that the
jinja2template is created withautoescapeenabled. This can be done by using theEnvironmentclass with theselect_autoescapefunction, which will automatically enable escaping for HTML and XML files. We will modify the code to create anEnvironmentobject withautoescapeset toselect_autoescape(['html', 'xml'])and use this environment to get the template.Suggested fixes powered by Copilot Autofix. Review carefully before merging.
