Summary

Wanwu before 0.6.3 by UnicomAI contains an insecure direct object reference that lets any authenticated enabled user delete other users' legacy AppKeys by supplying a numeric apiId. The flaw is tracked as CWE-639, an authorization bypass through a user-controlled key. An attacker with low privileges on the network can iterate sequential key IDs against the key deletion endpoint to revoke AppKeys across organizations, which breaks MCP and OpenAPI clients until owners issue new keys.
