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.
