SCA: security update for copier (GHSA-85v3-4m8g-hrh6)

medium Tenable Self-Hosted Container Security Plugin ID 439624

Description

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

 - Copier is a library and CLI app for rendering project templates. Prior to version 9.14.1, Copier's
 _subdirectory setting is documented as the subdirectory to use as the template root. However, the current
 implementation accepts parent-directory traversal such as .. and uses it directly when selecting the
 template root. As a result, a template can escape its own directory and make Copier render files from the
 parent directory without --UNSAFE. This issue has been patched in version 9.14.1. (CVE-2026-34726)

Solution

Update the copier library and its related packages to version 9.14.1 or later.
