Backstage: Catalog unprocessed read endpoints allow authenticated cross-owner data access without permission checks
Impact
The unprocessed entities read endpoints in @backstage/plugin-catalog-backend-module-unprocessed do not enforce permission authorization checks. Any authenticated user can access unprocessed entity records regardless of ownership. This is
an information disclosure vulnerability affecting Backstage installations using this module.
Patches
This is patched in @backstage/plugin-catalog-backend-module-unprocessed version 0.6.11, @backstage/plugin-catalog-unprocessed-entities-common version 0.0.15 and @backstage/plugin-catalog-unprocessed-entities version 0.2.30. Users should upgrade all packages.
Workarounds

without upgrading.
