GHSA-24C8-4792-22HX Scriban: array.insert_at index parameter DoS bypasses LoopLimit and LimitToString

Summary ArrayFunctions.InsertAt in Scriban allocates index - list.Count null entries in a tight C for loop with no bound on index. The function is exposed to template authors as array.insertat, and the fill loop ignores every existing safety control: LoopLimit, LimitToString, ObjectRecursionLimit...

Allocation of Resources Without Limits or Throttling

Overview Scriban is a Scriban is a fast, powerful, safe and lightweight scripting language and engine for .NET, which was primarily developed for text templating with a compatibility mode for parsing liquid templates. Today, not only Scriban can be used in text templating scenarios, but also can ...

GHSA-XW6W-9JJH-P9CR Scriban has Multiple Denial-of-Service Vectors via Unbounded Resource Consumption During Expression Evaluation

Summary Scriban's expression evaluation contains three distinct code paths that allow an attacker who can supply a template to cause denial of service through unbounded memory allocation or CPU exhaustion. The existing safety controls LimitToString, LoopLimit do not protect these paths, giving...

Scriban: Denial of Service via Unbounded Cumulative Template Output Bypassing LimitToString

Summary The LimitToString safety limit default 1MB since commit b5ac4bf can be bypassed to allocate approximately 1GB of memory by exploiting the per-call reset of currentToStringLength in ObjectToString. Each template expression rendered through TemplateContext.WriteSourceSpan, object triggers a...

GHSA-XCX6-VP38-8HR5 Scriban has Uncontrolled Recursion in `object.to_json` Causing Unrecoverable Process Crash via StackOverflowException

Summary The object.tojson builtin function in Scriban performs recursive JSON serialization via an internal WriteValue static local function that has no depth limit, no circular reference detection, and no stack overflow guard. A Scriban template containing a self-referencing object passed to...

Scriban: Uncontrolled Memory Allocation via string.pad_left/pad_right Allows Remote Denial of Service

Summary The built-in string.padleft and string.padright template functions in Scriban perform no validation on the width parameter, allowing a template expression to allocate arbitrarily large strings in a single call. When Scriban is exposed to untrusted template input — as in the official...

GHSA-C875-H985-HVRC Scriban: Built-in operations bypass LoopLimit and delay cancellation, enabling Denial of Service

Summary Scriban's LoopLimit only applies to script loop statements, not to expensive iteration performed inside operators and builtins. An attacker can submit a single expression such as 1..1000000 | array.size and force large amounts of CPU work even when LoopLimit is set to a very small value...
