 - Backstage is an open framework for building developer portals. Prior to 1.54.6, cloud storage catalog
 providers did not sufficiently validate object paths. A principal able to create or rename objects in a
 configured Azure Blob Storage or AWS S3 catalog source could cause catalog descriptors to be read from
 outside the intended storage boundary, limited to locations reachable with the backend's configured
 credentials. This issue is fixed in 1.54.6. (CVE-2026-106493)
