Name of the Vulnerable Software and Affected Versions Scriban versions prior to 7.0.0 Description The software fails to clear the CachedTemplates dictionary when the TemplateContext.Reset function is called, which allows cached templates to persist across reused contexts. This can be exploited...

Name of the Vulnerable Software and Affected Versions Scriban versions prior to 7.0.0 Description A denial-of-service issue exists where the LimitToString safety limit, which defaults to 1MB, can be bypassed. This occurs because the ObjectToString function resets the per-call length counter...

Name of the Vulnerable Software and Affected Versions Scriban versions prior to 7.0.0 Description Three distinct denial-of-service issues exist in expression evaluation that bypass safety controls. These issues involve unbounded string multiplication, uncontrolled BigInteger shift operations, and...

Summary TemplateContext.Reset claims that a TemplateContext can be reused safely on the same thread, but it does not clear CachedTemplates. If an application pools TemplateContext objects and uses an ITemplateLoader that resolves content per request, tenant, or user, a previously authorized inclu...

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-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...

GHSA-GRR9-747V-XVCP Scriban has an Infinite Recursion during Object Rendering Leads to Stack Overflow and Process Crash (Denial of Service)

When Scriban renders an object that contains a circular reference, it traverses the object's members infinitely. Because the ObjectRecursionLimit property defaults to unlimited, this behavior exhausts the thread's stack space, triggering an uncatchable StackOverflowException that immediately...

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...
