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...

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...

GHSA-5WR9-M6JW-XX44 Scriban: Sandbox escape due to TypedObjectAccessorcache bypassing MemberFilter after TemplateContext reuse

Summary TemplateContext caches type accessors by Type only, but those accessors are built using the current MemberFilter and MemberRenamer. When a TemplateContext is reused and the filter is tightened for a later render, Scriban still reuses the old accessor and continues exposing members that...

GHSA-5RPF-X9JG-8J5P Scriban Affected by Memory Exhaustion (OOM) via Unbounded String Generation (Denial of Service)

TemplateContext.LimitToString defaults to 0 unlimited. While Scriban implements a default LoopLimit of 1000, an attacker can still cause massive memory allocation via exponential string growth. Doubling a string for just 30 iterations generates over 1GB of text, instantly exhausting heap memory a...
