    Backstage: Cloud storage catalog locations may cross configured storage boundaries

    CVE-2026-106493 · GHSA-xvh9-35w9-42m4

    Affected
    • npm @backstage/plugin-catalog-backend-module-aws < 0.4.27
    Fixed in
    0.4.27· Vendor fix available
    Issue
    Impact Catalog entity providers for Azure Blob Storage and AWS S3 did not sufficiently validate storage object paths, which could allow catalog descriptors to be read from outside the intended storage boundary. Access is limited to locations reachable by the backend's configured credentials. Patches - @backstage/plugin-catalog-backend-module-azure version 0.3.21 - @backstage/plugin-catalog-backend-module-aws version 0.4.27 - @backstage/backend-defaults version 0.7.18 Workarounds - Restrict blob and object creation or renaming in configured catalog storage sources to trusted principals. - Scope Backstage's Azure and AWS reader credentials and network access to the intended storage boundaries. - Disable an affected catalog provider if those restrictions cannot be enforced.

    Recommended action: Upgrade to 0.4.27 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
