CVE-2026-74791Public exploitNetwork attack vector

Unauthorized template disclosure via stale include cache

Published Aug 16, 2026 · Updated Aug 16, 2026

Authorization bypass in Scriban before 7.0.0 allows remote attackers to read previously authorized template content via stale cached includes. TemplateContext.Reset() does not clear the CachedTemplates dictionary, and IncludeFunction.Invoke() reuses GetOrCreateTemplate() results without calling ITemplateLoader.Load() again when a path is already cached. Exposure requires TemplateContext reuse with Reset() between renders and a request-dependent ITemplateLoader; in that configuration, one request can prime admin- or tenant-specific include content for later unrelated renders.
