## Description

UnicomAI Wanwu through 0.6.5 contains a missing authorization vulnerability that allows any authenticated enabled user to revoke other users' AppKeys for arbitrary apps via the unpublish endpoint. Attackers can supply a target appId and appType from the exploration marketplace to delete other users' api_key rows across organizations, cutting off MCP and OpenAPI client access.
