Echo: tar: security update to 7.5.21

high Tenable Cloud Security Plugin ID 459414

Description

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

 - node-tar is a tar archive manipulation library for Node.js. Prior to 7.5.21, node-tar's filesFilter in
 src/list.ts uses the recursive mapHas helper to walk an archive entry path upward with path.dirname() and
 no segment cap when tar.t(...) or tar.x(...) receives a non-empty member-selection list. A crafted GNU L
 or PAX x long-path header with thousands of slash-separated segments reaches this.filter(entry.path,
 entry) in Parser[CONSUMEHEADER] in src/parse.ts before Unpack[CHECKPATH] applies maxDepth, causing an
 uncatchable RangeError stack overflow that terminates asynchronous and streaming Node.js consumers. This
 issue is fixed in version 7.5.21. (CVE-2026-73566)

Solution

Update the tar library and its related packages to version 7.5.21 or later.
