CVE-2024-28863: Isaacs Tar

Medium severity, CVSS 6.5. EPSS: 0.9% chance of exploitation in the next 30 days.

node-tar is a Tar for Node.js. node-tar prior to version 6.2.1 has no limit on the number of sub-folders created in the folder creation process. An attacker who generates a large number of sub-folders can consume memory on the system running node-tar and even crash the Node.js client within few seconds of running it using a path with too many sub-folders inside. Version 6.2.1 fixes this issue by preventing extraction in excessively deep sub-folders.

Affected products

• Isaacs Tar: before 6.2.1 (fixed in 6.2.1)
