GitHub Vulnerability Alerts

CVE-2026-29184

Impact

A malicious scaffolder template can bypass the log redaction mechanism to exfiltrate secrets provided run through task event logs.

The attack requires:

  • The ability to register a template in the catalog
  • A victim who executes the malicious template

Patches

Patched in @backstage/plugin-scaffolder-backend version 3.1.4

Workarounds

  • Implement a custom permission policy that restricts scaffolder.task.read so users can only read their own task logs
  • Restrict who can register templates in the catalog to trusted users only

Major Changes
  • 9b81a90: BREAKING - Removing the deprecated types and interfaces, there's no replacement for these types, and hopefully not currently used as they offer no value with the plugin being on the new backend system and no way to consume them.

    Affected types: CreateWorkerOptions, CurrentClaimedTask, DatabaseTaskStore, DatabaseTaskStoreOptions, TaskManager, TaskStore, TaskStoreCreateTaskOptions, TaskStoreCreateTaskResult, TaskStoreEmitOptions, TaskStoreListEventsOptions, TaskStoreRecoverTaskOptions, TaskStoreShutDownTaskOptions, TaskWorker and TemplateActionRegistry.
