The table's row-level security policies \"Allow org admin to insert\" and \"Allow org admin to update\" only verify that the caller has admin rights in the target organization (public.check_min_rights('admin', ...)); they do not require a pending invitation in tmp_users, acceptance of an invite token via /private/accept_invitation, any action by the target user, or the membership/role-consistency and anti-escalation checks enforced by the RBAC role-binding path. As a result, an authenticated user who is an admin of an organization can INSERT or UPDATE org_users rows directly to add any existing public.users account as an active member of that organization with user_right=\"admin\", bypassing the invitation and role-assignment workflow entirely. In testing, an account with no prior access to the organization or its apps could, after such a direct insert, read the organization and app and pass check_min_rights. All versions are affected and no patch was available at the time of publication.","state":0,"publishedAt":"2026-09-26T13:23:01.631+00:00","modifiedAt":"2026-09-30T17:20:11.439+00:00","affected":[{"ecosystem":"Vendor product","name":"capgo.app","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Cap-go\",\n                    \"product\": \"capgo.app\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"custom\",\n                            \"lessThanOrEqual\": \"*\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.7,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8,"severity":"HIGH"}],"references":["https://github.com/Cap-go/capgo.app/security/advisories/GHSA-w349-9mc3-8c5x","https://www.vulncheck.com/advisories/capgo-authentication-bypass-via-direct-postgrest-org-users-table-write"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-100623","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-100623","identifiers":["CVE-2026-100623"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
