# CVE-2026-100616: capgo.app Authentication Bypass via PostgREST customer\_id Mutation

- Severity: CVSS 7.0 (High), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2026-09-26 · Updated: 2026-10-05

## Affected

- Cap-go capgo.app: through \*

## Description

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.
