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.
AnalysisAI
Arbitrary CLR property writes in Scriban (the .NET templating engine) before 7.2.2 allow template code to mutate live host objects passed into a TemplateContext, bypassing C# setter-visibility rules entirely. Any object pushed via the documented ScriptObject pattern becomes fully writable, so template authors can set private, internal, and init-only setters as well as mass-assign public ones (e.g. …
