Description · from the CVE record

Scriban before 7.0.0 fails to clear the CachedTemplates dictionary when TemplateContext.Reset() is called, allowing cached templates to persist across reused contexts. Attackers can exploit request-dependent ITemplateLoader implementations to access previously authorized template content from earlier renders without triggering TemplateLoader.Load() again.
