{"schema":"threatline.record/2","record":{"id":"CVE-2026-100619","aliases":["GHSA-443r-w5p8-rhr2"],"summary":"Capgo OTA Manifest Poisoning via app_versions.manifest Bypass","details":"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.","categories":["Unclassified"],"product":"capgo.app","vendor":"Cap-go","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-100619","source_modified_at":"2026-09-30T17:20:09.972Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"capgo.app","vendor":"Cap-go","versions":[{"version":"0","status":"affected","versionType":"custom","lessThanOrEqual":"*"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":8.7,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00322,"percentile":0.23987,"score_date":"2026-10-23"},"published_at":"2026-09-26T13:22:58.881Z","modified_at":"2026-09-30T17:20:09.972Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-100619","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-30T17:20:09.972Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-100619","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/Cap-go/capgo.app/security/advisories/GHSA-443r-w5p8-rhr2","tags":["exploit"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/capgo-ota-manifest-poisoning-via-app-versions-manifest-bypass","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"total","assessed_at":"2026-09-28T17:13:54.114354Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-30T17:20:09.972Z","content_hash":"271fb8cd8608f37a38f09ed1ff9414e63ed12e73adda05357f387e283b2867c8"}}
