backstage · @backstage plugin-scaffolder-backend-module-confluence-to-markdown · Linuxfoundation backstage\/plugin-scaffolder-backend-module-confluence-to-markdown · Linuxfoundation backstage
Backstage is an open framework for building developer portals. Prior to 0.3.25, the @backstage/plugin-scaffolder-backend-module-confluence-to-markdown package is affected by improper repository path validation in a scaffolder backend module. An authenticated user who can execute an affected template and control its repository file location may cause generated content to be written outside the task workspace, within locations writable by the Backstage backend process. This issue is fixed in version 0.3.25.

backstage · @backstage plugin-scaffolder-backend-module-confluence-to-markdown · Linuxfoundation backstage\/plugin-scaffolder-backend-module-confluence-to-markdown · Linuxfoundation backstage
Backstage is an open framework for building developer portals. Prior to 0.3.25, the @backstage/plugin-scaffolder-backend-module-confluence-to-markdown package is affected by improper input validation in confluence to markdown scaffolder module. Insufficient input validation in the Confluence to Markdown scaffolder module could allow an attacker to influence file write operations during template execution. Exploitation requires a Backstage user to run a template that processes attacker-influenced Confluence content. This issue is fixed in version 0.3.25.

CVE-2026-106506 5.3 Moyenne
backstage · @backstage plugin-scaffolder-backend · Linuxfoundation backstage\/plugin-scaffolder-backend · Linuxfoundation backstage
Backstage is an open framework for building developer portals. Prior to 4.1.0, the @backstage/plugin-scaffolder-backend package is affected by improper input validation in scaffolder task list ordering. An authenticated Backstage user with permission to create and read relevant scaffolder tasks may be able to infer confidential task data under specific conditions. Successful exploitation requires retained task secrets, visibility of a target task, knowledge of the secret structure, and repeated requests. This issue is fixed in version 4.1.0.

CVE-2026-106504 6.5 Moyenne
backstage · @backstage plugin-scaffolder-backend · Linuxfoundation backstage\/plugin-scaffolder-backend · Linuxfoundation backstage
Backstage is an open framework for building developer portals. Prior to 4.1.0, the @backstage/plugin-scaffolder-backend package is affected by sensitive information exposure in scaffolder task logs. An authenticated user who can create and read scaffolder tasks may be able to observe sensitive values in task logs in deployments with restrictive action permissions and affected templates. Exploitation requires a denied action whose input contains such a value. This issue is fixed in version 4.1.0.

CVE-2026-106503 8.1 Élevée
backstage · @backstage plugin-scaffolder-backend · Linuxfoundation backstage\/plugin-scaffolder-backend · Linuxfoundation backstage
Backstage is an open framework for building developer portals. Prior to 3.3.1, 3.4.1, 4.0.3 and 4.1.0, the @backstage/plugin-scaffolder-backend package is affected by scaffolder action input authorization bypass. An authenticated user with access to affected Scaffolder templates could bypass configured action restrictions. Depending on integration credentials, this could grant unauthorized access to repositories and related source-control resources. This issue is fixed in versions 3.3.1, 3.4.1, 4.0.3 and 4.1.0.

CVE-2026-106502 5.3 Moyenne
backstage · @backstage plugin-scaffolder-backend · Linuxfoundation backstage\/plugin-scaffolder-backend · Linuxfoundation backstage
Backstage is an open framework for building developer portals. Prior to 4.1.0, the @backstage/plugin-scaffolder-backend package could expose sensitive information in Scaffolder task failure events. Under specific template and failure conditions, an authenticated user may retrieve backend-managed credentials used during task execution from affected task events. This issue is fixed in version 4.1.0.

CVE-2026-106501 9.6 Critique
backstage · @backstage plugin-scaffolder-backend · Linuxfoundation backstage\/plugin-scaffolder-backend · Linuxfoundation backstage
Backstage is an open framework for building developer portals. Prior to 3.3.1, 3.4.1, 4.0.3 and 4.1.0, the @backstage/plugin-scaffolder-backend package is affected by sensitive information exposure in scaffolder. 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. This issue is fixed in versions 3.3.1, 3.4.1, 4.0.3 and 4.1.0.

CVE-2026-106500 8.5 Élevée
backstage · @backstage plugin-scaffolder-backend · Linuxfoundation backstage\/plugin-scaffolder-backend · Linuxfoundation backstage
Backstage is an open framework for building developer portals. Prior to 3.3.1, 3.4.1, 4.0.3 and 4.1.0, the @backstage/plugin-scaffolder-backend package is affected by improper task state validation in scaffolder backend. An authenticated user with permission to create and access Scaffolder tasks may, under specific timing and deployment conditions, affect files accessible to the Backstage backend. If backend application files are writable, the confidentiality, integrity, and availability of the backend may be compromised. This issue is fixed in versions 3.3.1, 3.4.1, 4.0.3 and 4.1.0.

CVE-2026-106499 4.9 Moyenne
backstage · @backstage plugin-scaffolder-backend · Linuxfoundation backstage\/plugin-scaffolder-backend · Linuxfoundation backstage
Backstage is an open framework for building developer portals. Prior to 4.1.0, the @backstage/plugin-scaffolder-backend package could expose secret-derived values in Scaffolder task logs. 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 and exposed to users who can access the resulting task logs. This issue is fixed in version 4.1.0.

CVE-2026-106459 8.5 Élevée
backstage · @backstage plugin-scaffolder-backend-module-sentry · Linuxfoundation backstage\/plugin-scaffolder-backend-module-sentry · Linuxfoundation backstage
Backstage is an open framework for building developer portals. From 0.3.0 until 0.3.8, the @backstage/plugin-scaffolder-backend-module-sentry package is affected by improper input validation in sentry scaffolder actions. An authenticated internal user who can execute the affected actions may cause the backend to contact unintended destinations and disclose Sentry integration credentials. Subsequent impact depends on network reachability and the privileges granted to the configured token. This issue is fixed in version 0.3.8.
