Disclosure summary
### Impact 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. ### Patches Patched in `@backstage/plugin-techdocs-backend` version `2.2.4` ### Workarounds - Restrict access to the TechDocs backend to users who are permitted to view all stored documentation until an upgrade can be applied. - Keep the default backend authentication policy enabled.
