CVE-2026-100611
Capgo (capgo.app backend, versions ≤ 12.261.0) improperly restricts which roles the apikey_manager organization role may bind to newly created API keys.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.27%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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.
