CVE-2026-74791 PUBLISHED

Scriban before 7.0.0 Authorization Bypass via Stale Include Cache

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

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.
