Summary

Important: nodejs-nodemon security update

Details

Simple monitor script for use during development of a node.js app. For use during development of a node.js based application. nodemon will watch the files in the directory in which nodemon was started, and if any files change, nodemon will automatically restart your node application. nodemon does not require any changes to your code or method of development. nodemon simply wraps your node application and keeps an eye on any files that have changed. Remember that nodemon is a replacement wrapper for node, think of it as replacing the word "node" on the command line when you run your script.

Security Fix(es):

brace-expansion: Brace-expansion: Denial of Service due to exponential-time complexity (CVE-2026-13149)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

CVE-2026-13149 (GCVE-0-2026-13149)

Vulnerability from cvelistv5 – Published: 2026-06-30 08:30 – Updated: 2026-07-08 11:38

Summary

brace-expansion through 5.0.6 is vulnerable to denial of service. The expand() function exhibits exponential-time complexity in the number of consecutive non-expanding '{}' brace groups. An attacker who passes a crafted string to expand(), directly or transitively, can cause significant CPU consumption and event-loop blocking. The max option does not mitigate this, as it bounds the output size rather than the recursion work.

Severity

7.7 (High)
