GHSA-WGH7-7M3C-FX25
Vulnerability from github – Published: 2026-03-19 21:30 – Updated: 2026-07-06 13:06Scriban 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. In .NET, a StackOverflowException cannot be caught by standard try-catch blocks, resulting in the immediate and ungraceful termination of the entire hosting process.
Scriban utilizes a recursive-descent parser to process template expressions. While the library exposes an ExpressionDepthLimit property in its ParserOptions, this property defaults to null (disabled).
If an application accepts user-supplied templates (or dynamically constructs templates from untrusted input), an attacker can supply thousands of nested parentheses or blocks. As the parser recursively evaluates each nested layer, it consumes thread stack space until it exceeds the limits of the host OS, triggering a fatal crash.
Impact
An attacker can supply crafted input that triggers a StackOverflowException, causing immediate termination of the hosting process and resulting in a Denial of Service. In applications that process untrusted or user-controlled templates (e.g., web applications or APIs), this can be exploited remotely without authentication. The failure is not recoverable, requiring a full process restart and leading to service disruption.
Proof of Concept (PoC)
The following C# code demonstrates the vulnerability. Executing this code will immediately terminate the application process.
using Scriban;
// Creates a deeply nested expression: (((( ... (1) ... ))))
string nested = new string('(', 10000) + "1" + new string(')', 10000);
try {
// This will crash the entire process immediately
Scriban.Template.Parse("{{ " + nested + " }}");
} catch (Exception ex) {
// This catch block will never execute because StackOverflowException
Console.WriteLine("Caught exception: " + ex.Message);
}
Suggested Remediation
Update the ParserOptions constructor (or the internal parser initialization) to set a default value for ExpressionDepthLimit. A limit of 1000 (or even lower, such as 250 or 500) is generally more than enough for legitimate templates while safely preventing stack exhaustion.
public int? ExpressionDepthLimit { get; set; } = 250;
Alternatively, document the risk heavily and warn developers to manually set ExpressionDepthLimit if evaluating untrusted templates, though a secure-by-default approach is strongly preferred.

Vulnerability from github – Published: 2026-05-19 20:10 – Updated: 2026-07-06 22:53Impact
In deployments where untrusted users can provide SQL queries to be linted, an untrusted user can submit a malicious query with deliberate excessive nesting to any application using the parser to trigger a Denial of Service through resource exhaustion.
Patches
Versions 4.1.0 and up contain a configurable recursion limit, which is enabled by default, to prevent this manner of exploit.

Repeated receipt of the same packet can result in an extended denial of service condition for the device. Affected releases are Juniper Networks Junos OS: 16.1 versions prior to 16.1R7-S1; 16.2 versions prior to 16.2R2-S7; 17.1 versions prior to 17.1R2-S10, 17.1R3; 17.2 versions prior to 17.2R3; 17.3 versions prior to 17.3R3-S1; 17.4 versions prior to 17.4R2; 18.1 versions prior to 18.1R3; 18.2 versions prior to 18.2R2.

Mitigation
Ensure that an end condition will be reached under all logic conditions. The end condition may include checking against the depth of recursion and exiting with an error if the recursion goes too deep. The complexity of the end condition contributes to the effectiveness of this action.
Mitigation
Increase the stack size.
CAPEC-230: Serialized Data with Nested Payloads
Applications often need to transform data in and out of a data format (e.g., XML and YAML) by using a parser. It may be possible for an adversary to inject data that may have an adverse effect on the parser when it is being processed. Many data format languages allow the definition of macro-like structures that can be used to simplify the creation of complex structures. By nesting these structures, causing the data to be repeatedly substituted, an adversary can cause the parser to consume more resources while processing, causing excessive memory consumption and CPU utilization.
CAPEC-231: Oversized Serialized Data Payloads
An adversary injects oversized serialized data payloads into a parser during data processing to produce adverse effects upon the parser such as exhausting system resources and arbitrary code execution.
