Summary
In @backstage/plugin-catalog-backend-module-bitbucket-server from 0.4.0 to 0.5.15, inconsistent repository filtering in Bitbucket Server catalog event updates may allow ingestion of locations from repositories excluded by filters. Fixed in version 0.5.15.
Risk Assessment
Risk of unauthorized addition of catalog locations from repositories that should be excluded, potentially leading to uncontrolled expansion of the catalog scope.
Recommendation
Upgrade @backstage/plugin-catalog-backend-module-bitbucket-server to version 0.5.15 or later to ensure consistent filtering.

Original NVD description (English source)
Backstage is an open framework for building developer portals. From 0.4.0 until 0.5.15, the @backstage/plugin-catalog-backend-module-bitbucket-server package is affected by inconsistent repository filtering in bitbucket server catalog event updates. Deployments using event-driven updates in the Bitbucket Server catalog provider may ingest catalog locations from repositories that are excluded by the provider's configured project, repository, or archived-repository filters. An authenticated Bitbucket Server user who can push to a filtered-out repository that remains readable by the configured Backstage integration can trigger a legitimate repository event. The affected event path may then add a Location for that repository even though scheduled discovery excludes it. This issue is fixed in version 0.5.15.
