Cap-go capgo.app before 12.267.1 fails to validate target API key privilege during rotation, allowing an apikeymanager to rotate a higher-privileged orgsuperadmin sibling key and recover its plaintext credential. Attackers with apikeymanager role can enumerate same-owner API keys, rotate a stronger sibling through the PUT endpoint, and obtain the replacement plaintext secret to authenticate as the higher-privileged principal.

Cap-go capgo.app fails to validate that principals in channelpermissionoverrides 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.promotebundle to users outside the organization.
