Summary

Important: nodejs24 security update

Details

Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

Security Fix(es):

brace-expansion: Brace-expansion: Denial of Service due to exponential-time complexity (CVE-2026-13149)
tar: Node-tar: Denial of Service via malformed tar archive header (CVE-2026-59874)
tar: node-tar: Denial of Service via crafted gzip bomb (CVE-2026-59873)

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.

Severity

7.5 (High)

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)

CVE-2026-59873 (GCVE-0-2026-59873)

Vulnerability from cvelistv5 – Published: 2026-07-08 15:22 – Updated: 2026-07-08 19:41

Title

node-tar: Decompression/parse DoS via unlimited input

Summary

node-tar is a tar archive manipulation library for Node.js. Prior to 7.5.19, node-tar does not enforce hard upper bounds on total decompressed data, entry counts, or decompression ratio in extraction and parsing paths such as src/extract.ts, allowing a small crafted gzip bomb to exhaust disk space and CPU. This issue is fixed in version 7.5.19.

Severity

9.2 (Critical)

CVE-2026-59874 (GCVE-0-2026-59874)

Vulnerability from cvelistv5 – Published: 2026-07-08 15:23 – Updated: 2026-07-08 17:00

Title

node-tar: Negative tar entry size causes infinite loop in archive replace

Summary

node-tar is a tar archive manipulation library for Node.js. Prior to 7.5.18, tar.replace accepts a checksum-valid tar header with a negative base-256 encoded entry size, causing the archive scanner to make no progress while repeatedly parsing the same header. This issue is fixed in version 7.5.18.

Severity

8.7 (High)
