CVE-2026-108854 Details
Description
Wanwu before 0.6.3 contains an insecure direct object reference vulnerability that allows any authenticated enabled user to delete other users' legacy AppKeys by supplying a numeric apiId. Attackers can iterate sequential key IDs against DELETE /v1/appspace/app/key to revoke AppKeys across organizations, breaking MCP and OpenAPI clients until owners issue new keys.
A vulnerability allowing insecure direct object reference (IDOR) has been identified in UnicomAI Wanwu versions prior to 0.6.3. This vulnerability allows any authenticated user to delete another user's legacy AppKeys by providing a numeric ID. The deletion is performed through the DELETE /v1/appspace/app/key endpoint, which lacks proper ownership verification. As a result, attackers can exploit this vulnerability by iterating over key IDs to revoke AppKeys across different organizations, disrupting MCP and OpenAPI client operations until new keys are issued.
Users can upgrade to UnicomAI Wanwu version 0.6.3 or later, where this vulnerability has been fixed.
