{"id":"CVE-2026-100611","state":"PUBLISHED","title":"Capgo apikey_manager Role Privilege Escalation via Incomplete Role Deny-list","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.","publishedAt":"2026-09-26T13:22:53.315Z","updatedAt":"2026-09-30T17:20:05.706Z","severity":{"score":7.1,"label":"High","version":"4.0","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","source":"VulnCheck"},"assigner":"VulnCheck","products":["Cap-go capgo.app"],"affected":[{"vendor":"Cap-go","product":"capgo.app","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"12.261.0","versionType":"semver"}]}],"references":["https://github.com/Cap-go/capgo.app/security/advisories/GHSA-2x4j-p4pr-fvp8","https://www.vulncheck.com/advisories/capgo-apikey-manager-role-privilege-escalation-via-incomplete-role-deny-list"],"weaknesses":["CWE-269"],"ingestedAt":"2026-10-29T20:10:13.529Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/100xxx/CVE-2026-100611.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-100611","state":"PUBLISHED","datePublished":"2026-09-26T13:22:53.315Z","dateUpdated":"2026-09-30T17:20:05.706Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-09-26T02:30:34.353Z"},"containers":{"cna":{"title":"Capgo apikey_manager Role Privilege Escalation via Incomplete Role Deny-list","descriptions":[{"lang":"en","value":"Capgo (capgo.app backend, versions ≤ 12.261.0) improperly restricts which roles the apikey_manager organization role may bind to newly created API keys.
