SCA: security update for @backstage/plugin-techdocs (GHSA-gg96-f8wr-p89f)

high Tenable Cloud Security Plugin ID 415110

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. In versions of Backstage's Techdocs Plugin
 (`@backstage/plugin-techdocs`) prior to 0.9.5, a malicious internal actor can potentially upload
 documentation content with malicious scripts by embedding the script within an `object` element. This may
 give access to sensitive data when other users visit that same documentation page. The ability to upload
 malicious content may be limited by internal code review processes, unless the chosen TechDocs deployment
 method is to use an object store and the actor has access to upload files directly to that store. The
 vulnerability is patched in the `0.9.5` release of `@backstage/plugin-techdocs`. (CVE-2021-32661)
