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."}],"problemTypes":[{"descriptions":[{"lang":"en","description":"Incorrect Authorization","cweId":"CWE-863","type":"CWE"}]}],"affected":[{"vendor":"Cap-go","product":"capgo.app","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","versionType":"custom","lessThanOrEqual":"*"}]}],"metrics":[{"cvssV4_0":{"version":"4.0","vectorString":"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","attackVector":"NETWORK","attackComplexity":"LOW","attackRequirements":"NONE","privilegesRequired":"HIGH","userInteraction":"NONE","vulnConfidentialityImpact":"NONE","vulnIntegrityImpact":"LOW","vulnAvailabilityImpact":"HIGH","subConfidentialityImpact":"NONE","subIntegrityImpact":"NONE","subAvailabilityImpact":"NONE","baseScore":7,"baseSeverity":"HIGH","Automatable":"NOT_DEFINED","Recovery":"NOT_DEFINED","Safety":"NOT_DEFINED","exploitMaturity":"NOT_DEFINED","providerUrgency":"NOT_DEFINED","valueDensity":"NOT_DEFINED","vulnerabilityResponseEffort":"NOT_DEFINED"},"format":"CVSS"},{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:H","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"HIGH","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"LOW","availabilityImpact":"HIGH","baseScore":5.5,"baseSeverity":"MEDIUM"},"format":"CVSS"}],"references":[{"url":"https://github.com/Cap-go/capgo.app/security/advisories/GHSA-qp5h-v7x3-53cq","tags":["vendor-advisory"],"name":"GitHub Security Advisory (GHSA-qp5h-v7x3-53cq)"},{"name":"VulnCheck Advisory: capgo.app Authentication Bypass via PostgREST customer_id Mutation","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/capgo-app-authentication-bypass-via-postgrest-customer-id-mutation"}],"credits":[{"lang":"en","value":"Judel777","type":"reporter"}],"x_generator":{"engine":"vulncheck-endgame"}},"adp":[{"references":[{"url":"https://github.com/Cap-go/capgo.app/security/advisories/GHSA-qp5h-v7x3-53cq","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-10-05T16:03:51.138448Z","id":"CVE-2026-100616","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-05T16:03:57.612Z"}}]}}
