# CVE-2026-125397: NocoBase plugin-ai 2.1.0 through 2.2.41 Authorization Bypass via Sub-Agent Username Override

Status: published. Published: 2026-11-09. Updated: 2026-11-09.

NocoBase plugin-ai 2.1.0 through 2.2.41 contains an authorization bypass vulnerability in getAccessibleAIEmployee() that lets authenticated users access unassigned AI employees by overriding the role-derived filter with a supplied username. Attackers can use the dispatch-sub-agent-task tool to run ungranted AI employees with their tools and permissions, and get-ai-employee to read their prompts and tool configuration.
