identrail CVE-2026-59185：跨租戶 GitHub 安裝繫結未驗證擁有權
CVE-2026-59185 - identrail: Cross-tenant GitHub installation binding without ownership verification
identrail 的機器身份安全平臺在 1.0.2 之前的版本，允許未經驗證的 GitHub 安裝 ID 被跨租戶使用，進而取得目標組織的私有儲存庫資訊。
此漏洞已於 2026-10-28 公佈，並在 1.0.2 版本中修復。
此 CVE 允許跨租戶存取私有 GitHub 資料，提醒使用者即時升級至 1.0.2 以防止資料外洩。
identrail is a machine identity security platform for AWS, GitHub/OIDC, and Kubernetes. Prior to 1.0.2, the default-on `POST /v1/workspaces/:workspace_id/projects/:project_id/github/connect/complete` endpoint in `internal/api/router.go` accepts `installation_id` from the request body or `X-GitHub-Installation-ID` header without verifying the installation belongs to the caller's workspace. `CompleteGitHubConnection` in `internal/api/github_connect.go` rigorously binds `state` to the caller's tenant, workspace, and project, but checks only that the installation ID is positive before persisting it as the caller's connection. `ListInstallationRepositories` in `internal/connectors/github/repositories.go` invokes token creation through `internal/connectors/github/app.go` and `POST /app/installations/{installationId}/access_tokens`, using the application's JWT. An authenticated tenant who starts a legitimate connection can supply another customer's non-secret installation ID to read the victim organization's private repository inventory, content, and metadata or drive posture scans, provided identrail's GitHub App is installed there. The default-off V2 `CompleteGitHubConnector` path shares the installation-ownership gap and additionally matches pending `state` without rechecking caller scope. This issue is fixed in version 1.0.2.

Validate GitHub installation ID against the originating workspace to prevent cross-tenant repository access.
- Verify installation ID belongs to the initiating workspace.
- Bind installation ID to the pending state at start.
- Check installation's account matches authorized organization.
