CVE-2026-25547highbrace-expansion<=5.0.05.0.18.7

Summary

@isaacs/brace-expansion is vulnerable to a Denial of Service (DoS) issue caused by unbounded brace range expansion. When an attacker provides a pattern containing repeated numeric brace ranges, the library attempts to eagerly generate every possible combination synchronously. Because the expansion grows exponentially, even a small input can consume excessive CPU and memory and may crash the Node.js process.

Details

The vulnerability occurs because @isaacs/brace-expansion expands brace expressions without any upper bound or complexity limit. Expansion is performed eagerly and synchronously, meaning the full result set is generated before returning control to the caller.

For example, the following input:

{0..99}{0..99}{0..99}{0..99}{0..99}

produces:

100^5 = 10,000,000,000 combinations

This exponential growth can quickly overwhelm the event loop and heap memory, resulting in process termination.

Proof of Concept

The following script reliably triggers the issue.

Create poc.js:

const { expand } = require('@isaacs/brace-expansion');

const pattern = '{0..99}{0..99}{0..99}{0..99}{0..99}';

console.log('Starting expansion...');
expand(pattern);

Run it:

node poc.js

The process will freeze and typically crash with an error such as:

FATAL ERROR: JavaScript heap out of memory

Impact

This is a denial of service vulnerability. Any application or downstream dependency that uses @isaacs/brace-expansion on untrusted input may be vulnerable to a single-request crash.

An attacker does not require authentication and can use a very small payload to:

  • Trigger exponential computation
  • Exhaust memory and CPU resources
  • Block the event loop
  • Crash Node.js services relying on this library
Relevance:

The relevance of CVE-2026-25547 to the library/node:24-bookworm-slim image depends on the specific vulnerability details and its applicability to Node.js 24 or its dependencies. If it involves core Node.js functionality or a widely used library, it could be critical in production environments handling sensitive data or exposed to untrusted inputs. For minimal or isolated workloads, the risk might be lower. (Note: Relevance analysis is automatically generated and may require verification.)

Severity Levels

Exploitation could lead to severe consequences, such as system compromise or data loss. Requires immediate attention.

Vulnerability could be exploited relatively easily and lead to significant impact. Requires prompt attention.

Exploitation is possible but might require specific conditions. Impact is moderate. Should be addressed in a timely manner.

Exploitation is difficult or impact is minimal. Address when convenient or as part of regular maintenance.

Severity is not determined, informational, or negligible. Review based on context.

About the CVE Scanner

What is a CVE?

CVE stands for Common Vulnerabilities and Exposures. It is a standardized identifier for known security vulnerabilities, allowing developers and organizations to track and address potential risks effectively. For more information, visit cve.mitre.org.

About the CVE Scanner

The CVE Scanner is a powerful tool that helps you identify known vulnerabilities in your Docker images. By scanning your images against a comprehensive database of Common Vulnerabilities and Exposures (CVEs), you can ensure that your applications are secure and up-to-date. For more details, checkout the NIST CVE Database.

How the CVE Scanner Works

The CVE Scanner analyzes your Docker images against a comprehensive database of known vulnerabilities. It uses Docker Scout under the hood to provide detailed insights into affected packages, severity levels, and available fixes, empowering you to take immediate action.

Why CVE Scanning is Essential for Your Docker Images

With the rise of supply chain attacks, ensuring the security of your applications has become more critical than ever. CVE scanning plays a vital role in identifying vulnerabilities that could be exploited by attackers, especially those introduced through dependencies and third-party components. Regularly scanning and securing your Docker images is essential to protect your applications from these evolving threats.

Benefits of CVE Scanning

  • Enhanced Security: Detect and mitigate vulnerabilities before they are exploited.
  • Compliance: Meet industry standards and regulatory requirements for secure software.
  • Proactive Maintenance: Stay ahead of potential threats by addressing vulnerabilities early.

The Importance of Patching Docker Images

Patching your Docker images is a critical step in maintaining the security and stability of your applications. By regularly updating your images to include the latest security patches, you can address known vulnerabilities and reduce the risk of exploitation. This proactive approach ensures that your applications remain resilient against emerging threats and helps maintain compliance with security best practices.
