Description OSIDB Bzimport 2026-05-14 16:01:59 UTC 
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.
