Echo: tar: security update to 7.5.8

high Tenable Cloud Security Plugin ID 465956

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - node-tar is a full-featured Tar for Node.js. When using default options in versions 7.5.7 and below, an
 attacker-controlled archive can create a hardlink inside the extraction directory that points to a file
 outside the extraction root, enabling arbitrary file read and write as the extracting user. Severity is
 high because the primitive bypasses path protections and turns archive extraction into a direct filesystem
 access primitive. This issue has been fixed in version 7.5.8. (CVE-2026-26960)

Solution

Update the tar library and its related packages to version 7.5.8 or later.
