Echo: SharpCompress: security update to 0.23.0+echo.1

medium Tenable Self-Hosted Container Security Plugin ID 474018

Description

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

 - SharpCompress is a fully managed C# library to deal with many compression types and formats. In 0.47.4 and
 earlier, a path traversal vulnerability in IArchive.WriteToDirectory() allows a malicious archive to
 create directories outside the intended extraction root. For TAR archives, this can be escalated to
 arbitrary file writes by chaining with a symlink entry, giving a full write primitive on the target
 filesystem subject to the permissions of the running process. (CVE-2026-44788)

Solution

Update the SharpCompress library and its related packages to version 0.23.0+echo.1 or later.
