CVE-2026-74783 Scriban 6.6.0 through 7.2.0 Parser Recursion Denial of Service

Scriban versions 6.6.0 through 7.2.0 contain a non-enforcing ExpressionDepthLimit guard that fails to stop recursive descent parsing of deeply nested expressions. Attackers can supply templates with deeply nested parentheses, array initializers, object initializers, or unary operators to trigger ...

GHSA-6Q7J-XR26-3H2C Scriban: ExpressionDepthLimit guard is non-enforcing — parser-recursion DoS in 6.6.0–7.2.0 (incomplete fix for GHSA-wgh7-7m3c-fx25 / GHSA-p6q4-fgr8-vx4p)

Summary The ExpressionDepthLimit parser guard in Scriban does not actually stop parsing — it only logs a non-fatal error and lets recursive descent continue. As a result, a template containing a deeply nested expression parentheses, array initializers, object initializers, or unary operators driv...

GHSA-P6Q4-FGR8-VX4P Scriban has a Stack Overflow via Nested Array Initializers That Bypass the ExpressionDepthLimit Fix

Summary StackOverflowException via nested array initializers bypasses ExpressionDepthLimit fix GHSA-wgh7-7m3c-fx25 Details The recent fix for GHSA-wgh7-7m3c-fx25 uncontrolled recursion in parser added ExpressionDepthLimit defaulting to 250. However, deeply nested array initializers ... recurse...

Scriban has Uncontrolled Recursion in Parser Leads to Stack Overflow and Process Crash (Denial of Service)

Scriban is vulnerable to an uncontrolled process crash resulting in a Denial of Service. Because the recursive-descent parser does not enforce a default limit on expression depth, an attacker who controls template input can craft a heavily nested template that triggers a StackOverflowException. I...
