Title
Capgo apikey_manager Role Privilege Escalation via Incomplete Role Deny-list
Summary
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.

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 \u2014 higher than those roles\u0027 ranks (68, 66, 58, 57) \u2014 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\u0027s apps.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Sightings

Author Source Type Date Other

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
