CVE-2026-45374 – CodeWhale: task_create Insecure Defaults Enable RCE via Prompt Injection in Project Files

CVE ID :CVE-2026-45374

Published : May 28, 2026, 6:16 p.m. | 15 minutes ago

Description :CodeWhale is a DeepSeek + MiMo coding agent in terminal. Prior to 0.8.26, the task_create tool spawns durable sub-agents that inherit two insecure defaults, allow_shell defaults to true (config.rs:1499: self.allow_shell.unwrap_or(true)) and auto_approve defaults to true (task_manager.rs:297: auto_approve: Some(true)). When a user approves a task_create call (which requires ApprovalRequirement::Required), they approve what appears to be a benign work prompt. However, the spawned sub-agent silently receives unrestricted, unapproved shell access. This vulnerability is fixed in 0.8.26.

Severity: 9.6 | CRITICAL
