CVE-2026-9810Public exploitNetwork attack vector

Unauthenticated administrator access via unbound OAuth tokens

Published Jul 17, 2026 · Updated Jul 17, 2026

Privilege escalation in AI Chatbot & Workflow Automation by AIWU before 1.5.4 allows remote attackers to gain administrator access via OAuth. The MCP OAuth implementation issues authorization codes without requiring an authenticated capable WordPress user, then accepts tokens without binding them to the approving user and restores them as the first administrator. MCP and OAuth 2.1 must be enabled, after which the public OAuth flow exposes privileged MCP tools that can create users and assign the administrator role.
