Official description

Scriban before 7.2.2 contains an access-modifier bypass vulnerability in TypedObjectAccessor that allows template code to write CLR object properties without setter-visibility checks. Attackers can modify properties with private, internal, or init-only setters, and perform mass assignment on public-setter properties, permanently altering live host objects after template rendering.
