Description

Backstage is an open framework for building developer portals. Prior to 3.9.1, the @backstage/plugin-catalog-backend package is affected by inconsistent enforcement of allowed location types during catalog processing. Under certain configurations, the catalog backend could process location types that were not intended to be allowed, potentially leading to unintended file access on the backend host. This issue is fixed in version 3.9.1.

Affected configurations

• linuxfoundation backstage plugin-catalog-backend (< 3.9.1) • linuxfoundation backstage (< 1.54.6)
