Detailsinfo

A vulnerability was found in Cap-go capgo.app (the affected version unknown). It has been declared as problematic. Affected by this vulnerability is an unknown part of the file supabase/functions/_backend/public/organization/put.ts of the component Row-level security policy. The manipulation of the argument customer_id with an unknown input leads to a privileges management vulnerability. The CWE definition for the vulnerability is CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. As an impact it is known to affect integrity, and availability. The summary by CVE is:

capgo.app is an over-the-air update platform for Capacitor apps. In all versions prior to a fix, the row-level security UPDATE policy on the public.orgs table permits an organization admin (a user holding org.update_settings) to update the entire row, including the internal billing pointer column customer_id. The official organization update endpoint (supabase/functions/_backend/public/organization/put.ts) allowlists only a small set of editable settings fields and excludes customer_id, and the private Stripe billing route separately requires the org.update_billing permission. By sending an update directly to Supabase PostgREST, an authenticated org admin without org.update_billing can null or corrupt the organization's Stripe customer pointer, causing plan and billing checks that trust orgs.customer_id to fail and moving the organization from a valid paid plan state to unpaid/no-plan behavior. At the time of the advisory no patched version was available.
