What is CVE-2026-74783?

Scriban versions 6.6.0 to 7.2.0 are vulnerable to a Denial of Service attack due to a misconfigured ExpressionDepthLimit. This issue allows attackers to craft templates with nested structures that can trigger a StackOverflowException, causing the host process to terminate uncontrollably. This vulnerability can be exploited by providing specially designed templates featuring deeply nested parentheses and complex initializers, leading to severe service disruptions.
