Summary

Cap-go capgo.app fails to validate that principals in channel_permission_overrides belong to the organization, allowing authenticated app/org admins to grant channel permissions to non-member users. Attackers with admin privileges can insert override rows with arbitrary external user UUIDs to grant channel-scoped permissions such as channel.promote_bundle to users outside the organization.

Risk Assessment

An organization admin can grant channel permissions to users outside the organization, potentially leading to unauthorized access to channel functions. This may result in privilege escalation and compromise of application security.

Recommendation

No patch is available; monitor official Capgo communications and apply the update when available. Consider manually reviewing channel_permission_overrides entries and restricting admin privileges.
