CVE-2026-100617: Missing Authorization in Cap-go capgo.app
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.
AI Analysis
Technical Summary
Cap-go capgo.app does not validate that principals specified in channel_permission_overrides are members of the organization. Authenticated app or organization admins can exploit this by inserting override rows with arbitrary external user UUIDs, granting channel-scoped permissions such as channel.promote_bundle to non-member users. This missing authorization check leads to unauthorized permission grants within channels.
Potential Impact
Attackers with admin privileges can grant channel-scoped permissions to external users who are not members of the organization, potentially leading to unauthorized actions within channels. This could compromise channel integrity and control, impacting confidentiality and integrity of channel operations.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict admin privileges to trusted personnel and monitor for unauthorized permission overrides.
