Privilege escalation in Cap-Go @Capgo/cli
CVE-2026-100620
Capgo CLI (npm package @capgo/cli) through 7.98.2 is affected by an over-permissioned service account in its Android onboarding flow. When onboarding via Google OAuth, the CLI invites the generated Google Play service account with the account-wide Play Console permission CAN_MANAGE_DRAFT_APPS_GLOBAL (passed as developerAccountPermissions in the Android Publisher API User create request), even though the user-facing flow states the service account is invited into a single confirmed app with release-only permissions. As a result, anyone who obtains the generated service account key (PLAY_CONFIG_JSON) can create, edit, and delete draft apps across the entire Google Play developer account rather than being limited to the selected package. No patched version was available at the time of publication.
