CVE-2026-106493 · Backstage: Cloud storage catalog locations may cross configured storage boundaries
This page contains facts from public vulnerability sources. Check the original advisory before updating.
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.
