SCA: security update for @backstage/techdocs-common (GHSA-pgf8-28gg-vpr6)

medium Tenable Cloud Security Plugin ID 417510

Description

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

 - Backstage is an open platform for building developer portals, and techdocs-common contains common
 functionalities for Backstage's TechDocs. In `@backstage/techdocs-common` versions prior to 0.6.3, a
 malicious actor could read sensitive files from the environment where TechDocs documentation is built and
 published by setting a particular path for `docs_dir` in `mkdocs.yml`. These files would then be available
 over the TechDocs backend API. This vulnerability is mitigated by the fact that an attacker would need
 access to modify the `mkdocs.yml` in the documentation source code, and would also need access to the
 TechDocs backend API. The vulnerability is patched in the `0.6.3` release of `@backstage/techdocs-common`.
 (CVE-2021-32662)
