CVE-2026-100617— Cap-go capgo.app Authorization Bypass via channel_permission_overrides

Quick assessment

Affected
Cap-go capgo.app
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Cap-go（capgo.app）未能验证频道权限覆盖（channel_permission_overrides）中的主体是否属于当前组织，从而导致经过身份验证的应用或组织管理员可以向非成员用户授予频道权限。拥有管理员权限的攻击者可以插入带有任意外部用户 UUID 的覆盖记录，从而向组织外部用户授予频道范围内的权限（例如 channel.promote_bundle）。

Vulnerability Description
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.
