CVE-2026-74790 PUBLISHED

Scriban before 7.0.0 MemberFilter Bypass via TemplateContext Cache

Assigner: VulnCheck
Reserved: 16.08.2026 Published: 16.08.2026 Updated: 16.08.2026

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.
