Recommended action: Upgrade Flask to >=2.0, or change imports to from markupsafe import escape, Markup; if Flask 1.x must stay, pin Jinja2<3.1 (and see the MarkupSafe/itsdangerous pins).
Option: Upgrade Flask to >=2.0, or change imports to from markupsafe import escape, Markup [evidence: official_recommended_action]
Applies when: Jinja2>=3.1.0 (released 2022-03-24) with Flask<2.0 or code importing escape/Markup from jinja2
Steps:
1. pip install -U 'flask>=2'
2. or replace from jinja2 import escape/Markup with from markupsafe import escape, Markup
3. or pin 'jinja2<3.1' together with 'markupsafe<2.1' and 'itsdangerous<2.1' for Flask 1.x
Expected: Import/call succeeds on the new version
