A principal holding an app-scoped upload/write/all API key (upload+ rights) or an authenticated user with write+ rights on an app can update public.app_versions.manifest on a version whose storage_provider is 'r2-direct', which is not covered by the bundle content-lock check. The on_version_update async worker trusts record.manifest and, using the service-role Supabase client, inserts the attacker-controlled file_name, file_hash, and s3_path into public.manifest before clearing app_versions.manifest. When a channel points to the crafted version, the /updates endpoint returns the service-role-created manifest entry as a client-facing download_url, enabling OTA manifest poisoning through a trusted async worker path. All versions are affected; no patch was available at the time of publication.","state":0,"publishedAt":"2026-09-26T13:22:58.881+00:00","modifiedAt":"2026-09-30T17:20:09.972+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-443r-w5p8-rhr2","https://www.vulncheck.com/advisories/capgo-ota-manifest-poisoning-via-app-versions-manifest-bypass"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-100619","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-100619","identifiers":["CVE-2026-100619"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
