SCA: security update for @backstage/plugin-techdocs-node (GHSA-w669-jj7h-88m9)

medium Tenable Self-Hosted Container Security Plugin ID 437417

Description

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

 - Backstage is an open framework for building developer portals, and @backstage/plugin-techdocs-node
 provides common node.js functionalities for TechDocs. In versions of @backstage/plugin-techdocs-node prior
 to 1.13.11 and 1.14.1, a path traversal vulnerability in the TechDocs local generator allows attackers to
 read arbitrary files from the host filesystem when Backstage is configured with `techdocs.generator.runIn:
 local`. When processing documentation from untrusted sources, symlinks within the docs directory are
 followed by MkDocs during the build process. File contents are embedded into generated HTML and exposed to
 users who can view the documentation. This vulnerability is fixed in` @backstage/plugin-techdocs-node`
 versions 1.13.11 and 1.14.1. Some workarounds are available. Switch to `runIn: docker` in `app-
 config.yaml` and/or restrict write access to TechDocs source repositories to trusted users only.
