CVE-2026-44374
This is an information disclosure vulnerability affecting Backstage installations using this module.
Does this matter?
Lower severity and a low EPSS score (0.17%). Track it; it rarely justifies an emergency change on its own.
Description
Backstage is an open framework for building developer portals. Prior to 0.6.11, 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. 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.
