Quick assessment

Affected
agenticmail @agenticmail/api
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

AgenticMail是AgenticMail公司的一款面向人工智能代理的电子邮件、短信和电话基础设施。 AgenticMail 0.9.64之前版本存在授权问题漏洞，该漏洞源于授权绕过问题，允许低权限认证代理通过向GET /api/agenticmail/tasks/pending接口提供目标代理名称枚举其他代理的待办/已认领任务，获取任务ID和有效载荷，进而利用任务变异端点跨代理认领、完成或失败任务，导致预期的能力模型失效。

Vulnerability Title
AgenticMail: Cross-agent task authorization bypass in AgenticMail API
Source: CVE Program / CVE List V5
Vulnerability Description
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.
