The PUT /app/:id endpoint accepts a user-controlled `icon` value, normalizes it, and stores it in public.apps.icon_url without verifying that the image path belongs to the target app's own image namespace (e.g. org/{owner_org}/{app_id}/...). Updating apps.icon_url fires the on_app_update trigger, whose worker reads record.icon_url and calls cleanStoredImageMetadata(), which runs with service-role credentials (supabaseAdmin()) and downloads and re-uploads the referenced storage object with upsert: true. As a result, an authenticated holder of an app-limited write API key can cause the privileged worker to rewrite an out-of-scope private image object (for example an organization logo) that the key cannot read or write directly under Supabase Storage RLS. All versions are affected; no patched version was available at the time of the advisory.","state":0,"publishedAt":"2026-09-26T13:22:58.212+00:00","modifiedAt":"2026-09-30T17:20:09.244+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:N/UI:N/VC:H/VI:N/VA:N/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:C/C:L/I:H/A:N","score":8.5,"severity":"HIGH"}],"references":["https://github.com/Cap-go/capgo.app/security/advisories/GHSA-669c-gwrr-hc53","https://www.vulncheck.com/advisories/capgo-app-icon-update-privilege-escalation-via-service-role-worker"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-100618","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-100618","identifiers":["CVE-2026-100618"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
