{"id":"CVE-2026-100619","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-100619","generatedAt":"2026-10-28T03:39:47.582Z","title":"Capgo (capgo.app) blocks direct user inserts into the public.manifest table with a RESTRICTIVE row-level security policy, but that restriction can be bypassed indirectly.","description":"Capgo (capgo.app) blocks direct user inserts into the public.manifest table with a RESTRICTIVE row-level security policy, but that restriction can be bypassed indirectly. 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.","published":"2026-09-26T14:16:43.000Z","lastModified":"2026-09-30T18:18:00.000Z","status":"Deferred","sourceIdentifier":"disclosure@vulncheck.com","cvss":{"version":"4.0","score":8.7,"severity":"HIGH","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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-266"],"affected":[],"epss":{"score":0.00407,"percentile":0.34773,"date":"2026-10-27","history":[{"date":"2026-09-27","score":0.00322,"percentile":0.22695}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.41%).
