Summary

UnicomAI Wanwu before 0.6.3 contains an insecure direct object reference flaw, tracked as CWE-639, in which the DELETE /v1/appspace/app endpoint does not check ownership of the supplied appId. An authenticated low-privileged user can delete other tenants' agent or RAG applications by supplying their IDs, which permanently removes the applications, workflows, conversations, and associated data. The CVSS 4.0 vector rates the attack as network-reachable with low complexity and no user interaction.
