CVE-2026-57494Public exploitNetwork attack vector

Cross-agent task disclosure and mutation via unchecked identifiers

Published Jul 20, 2026 · Updated Jul 20, 2026

Authorization bypass in AgenticMail @agenticmail/api before 0.9.64 allows remote authenticated users to read and alter other agents' tasks. The pending-task route trusts a caller-supplied assignee name, while task mutation routes accept disclosed task IDs without checking the caller's relationship to the task. Any agent API key is sufficient to read another agent's task payloads and claim, complete, fail, or submit results for those tasks.
