{"id":"CVE-2026-100611","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-100611","generatedAt":"2026-10-28T02:24:58.426Z","title":"Capgo (capgo.app backend, versions ≤ 12.261.0) improperly restricts which roles the apikey_manager organization role may bind to newly created API keys.","description":"Capgo (capgo.app backend, versions ≤ 12.261.0) improperly restricts which roles the apikey_manager organization role may bind to newly created API keys. When an authenticated user holding only apikey_manager (permissions org.manage_apikeys and org.read) calls POST /apikey with a JWT session, the only checks applied are the org.manage_apikeys permission, a fixed deny-list of assignable role names (APIKEY_MANAGER_DENIED_ASSIGNABLE_ROLES in public/apikey/scope.ts), and a priority-rank comparison in createRoleBindingForPrincipal (private/role_bindings.ts). No check verifies that the caller actually holds the permissions conferred by the role being assigned. Because the deny-list omits the deploy roles app_developer, app_uploader, channel_developer and channel_uploader, and apikey_manager is seeded with priority_rank 78 — higher than those roles' ranks (68, 66, 58, 57) — the rank check also passes. As a result, an apikey_manager who cannot upload bundles or promote channels can mint an API key bound to a deploy role and use it to push arbitrary OTA JavaScript updates to all end users of the organization's apps. As of the advisory publication no patched version was available.","published":"2026-09-26T14:16:42.000Z","lastModified":"2026-09-30T18:17:59.000Z","status":"Deferred","sourceIdentifier":"disclosure@vulncheck.com","cvss":{"version":"4.0","score":7.1,"severity":"HIGH","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/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-269"],"affected":[],"epss":{"score":0.00267,"percentile":0.18629,"date":"2026-10-26","history":[{"date":"2026-09-27","score":0.00221,"percentile":0.11367}]},"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 (0.27%).
