NVD CVE.org

AI Analysis

No AI analysis yet.

Description

Scriban before 7.0.0 caches TypedObjectAccessor by Type only without considering MemberFilter changes, allowing reused TemplateContext instances to expose members that should be hidden. Attackers can access filtered properties and fields by reusing a TemplateContext after tightening its MemberFilter, bypassing sandbox policies across requests or tenants.
