CVE-2026-57494
No affected components available
AgenticMail gives AI agents real email addresses and phone numbers. In @agenticmail/api prior to version 0.9.64, a low-privileged authenticated AgenticMail agent can enumerate another agent's pending/claimed tasks by supplying the target agent name to GET /api/agenticmail/tasks/pending?assignee=<name>. The returned task objects include the task IDs and payloads. The same task IDs can then be used with the capability-style task mutation endpoints (/tasks/:id/claim, /tasks/:id/result, /tasks/:id/complete, /tasks/:id/fail) to claim, complete, or fail tasks assigned to a different agent. Because ordinary authenticated agents can discover agent names through GET /api/agenticmail/accounts/directory, the task ID effectively stops being a secret capability. This turns the intended capability model into a cross-agent authorization bypass. Version 0.9.64 contains a fix.
