SCA: security update for @backstage/catalog-model, @backstage/core-components, @backstage/plugin-catalog-backend (GHSA-7hv8-3fr9-j2hv)

medium Tenable Self-Hosted Container Security Plugin ID 412095

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. `@backstage/catalog-model` prior to version
 1.2.0, `@backstage/core-components` prior to 0.12.4, and `@backstage/plugin-catalog-backend` prior to
 1.7.2 are affected by a cross-site scripting vulnerability. This vulnerability allows a malicious actor
 with access to add or modify content in an instance of the Backstage software catalog to inject script
 URLs in the entities stored in the catalog. If users of the catalog then click on said URLs, that can lead
 to an XSS attack. This vulnerability has been patched in both the frontend and backend implementations.
 The default `Link` component from `@backstage/core-components` version 1.2.0 and greater will now reject
 `javascript:` URLs, and there is a global override of `window.open` to do the same. In addition, the
 catalog model v0.12.4 and greater as well as the catalog backend v1.7.2 and greater now has additional
 validation built in that prevents `javascript:` URLs in known annotations. As a workaround, the general
 practice of limiting access to modifying catalog content and requiring code reviews greatly help mitigate
 this vulnerability. (CVE-2023-25571)
