CVE-2026-57494: CWE-639: Authorization Bypass Through User-Controlled Key in agenticmail @agenticmail/api
AgenticMail's @agenticmail/api prior to version 0.9.64 contains an authorization bypass vulnerability. Low-privileged authenticated agents can enumerate and manipulate tasks assigned to other agents by exploiting predictable task IDs and accessible agent names. This allows unauthorized claiming, completing, or failing of tasks belonging to other agents. The issue is fixed in version 0.9.64.
AI Analysis
Technical Summary
CVE-2026-57494 is an authorization bypass vulnerability in the @agenticmail/api component of AgenticMail before version 0.9.64. The flaw arises because authenticated agents can enumerate other agents' pending or claimed tasks by specifying the target agent's name in a GET request. Since agent names are discoverable via a directory endpoint, task IDs cease to be secret capabilities. These task IDs can then be used with task mutation endpoints to manipulate tasks assigned to other agents, violating the intended capability-based access control model. The vulnerability is addressed in version 0.9.64.
Potential Impact
An authenticated low-privileged agent can access and manipulate tasks assigned to other agents, including claiming, completing, or failing those tasks. This breaks the intended authorization model and could lead to unauthorized task manipulation within the AgenticMail system.
Mitigation Recommendations
Upgrade to @agenticmail/api version 0.9.64 or later, where this authorization bypass vulnerability is fixed. No other mitigation is indicated by the vendor advisory.
