CyberRota Analysis

AI-Generated

The vulnerability allows unauthorized access to catalog descriptors in Azure Blob Storage or AWS S3 due to insufficient validation of object paths in Backstage versions prior to 1.54.6. This could enable a principal with object creation or renaming capabilities to read sensitive data from unintended storage locations. Organizations using Backstage for developer portals should prioritize upgrading to version 1.54.6 to mitigate this risk.

Original NVD Description

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.
