NVD 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.

🚨Critical - Scriban Template Sandbox Escape via TypedObjectAccessor Setter Bypass (CVE-2026-73061) Scriban's TypedObjectAccessor bypasses access-modifier checks when setting CLR properties from template code, allowing writes to private/internal/init-only setters and mass assignment to public setters. Untrusted templates can permanently mutate live host objects after rendering, leading to privilege/config tampering. 👉Affected: scriban < 7.2.2 | Upgrade to 7.2.2
Post summary
A critical Scriban template sandbox escape (CVE‑2026‑73061) enables untrusted templates to write to protected CLR properties, causing privilege and configuration tampering; upgrading to version 7.2.2 resolves the vulnerability.
