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.
