GHSA-H53X-HJX6-25GR Backstage: Unsupported catalog cluster authentication mode in kubernetes backend

Impact Deployments using catalog cluster discovery may be affected when catalog contributors can create or modify kubernetes-cluster Resource entities. With the required endpoint permissions and pod RBAC, the backend can use its local in-cluster identity, potentially exposing Kubernetes resources...

Backstage: Improper authorization enforcement for TechDocs static content

Impact An authenticated user with access to one TechDocs documentation site could craft a URL able to read documentation belonging to a different entity. This only affects deployments using the external TechDocs builder with an external storage provider S3, GCS, etc. and the permission framework...

Backstage: Improper input validation in TechDocs static content requests

Impact When using the Azure Blob Storage provider, an authenticated Backstage user may be able to read restricted TechDocs content when entity-level permissions are enabled. Deployments that intentionally disable the default backend authentication policy may have broader exposure. Patches Patched...

Backstage: Cloud storage catalog locations may cross configured storage boundaries

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...

GHSA-XVH9-35W9-42M4 Backstage: Cloud storage catalog locations may cross configured storage boundaries

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...

Backstage: Improper URL validation in catalog entity placeholder resolution

Impact An authenticated Backstage user could craft a catalog entity with placeholder directives that reference resources outside the entity's source repository. Under certain configurations, this could allow access to data not intended to be available to the user. Patches Patched in...

GHSA-G2V8-7JHW-PP8P Backstage: Sensitive information exposure in Scaffolder

Impact An authenticated Backstage user who can read another user's Scaffolder task may receive internal execution data. In deployments where that data contains credentials for an external service, this may permit disclosure and unauthorized changes in that external service. Patches Patched in...

GHSA-MFVQ-X7VR-RGQG Backstage: Secret-derived values may be exposed in scaffolder task logs

Impact Deployments that configure sensitive scaffolder.defaultEnvironment.secrets and allow an attacker to create or modify Scaffolder templates are affected. A template author could cause secret-derived values used during template iteration to be persisted in task logs, exposing those values to...

GHSA-7HFW-GRCM-CQM6 Backstage: Incorrect authorization in scaffolder task listing

Impact An authenticated internal user may be able to view metadata for scaffolder tasks outside the visibility intended by a deployment's permission policy. Stored task secrets are not included in the affected response, and no integrity or availability impact was identified. Patches Patched in...

CVE-2026-106580

A flaw was found in ImageMagick. A missing security policy check in the CUT encoder allows a local attacker to execute a crafted encoding operation that bypasses established restrictions. Successful exploitation can lead to unauthorized data reading information disclosure or cause the application...

CVE-2026-106579

A flaw was found in ImageMagick. This issue allows an attacker to bypass access controls and read restricted files, leading to unauthorized information disclosure. By supplying a specially crafted image to a system configured with security policies that restrict image decoders the coder domain, t...
