CVE-2026-106490 · Backstage: Improper input validation in TechDocs static content requests
This page contains facts from public vulnerability sources. Check the original advisory before updating.
Backstage is an open framework for building developer portals. Prior to 2.2.4, the @backstage/plugin-techdocs-backend package is affected by improper input validation in techdocs static content requests. When using the Azure Blob Storage provider, an authenticated Backstage user may be able to read restricted TechDocs content when entity-level permissions are enabled. Deployments that intentionally disable the default backend authentication policy may have broader exposure. This issue is fixed in version 2.2.4.
