CVE-2025-54131: cursor Command Injection — Fix

Description

Cursor is a code editor built for programming with AI. In versions below 1.3, an attacker can bypass the allow list in auto-run mode with a backtick (`) or $(cmd). If a user has swapped Cursor from its default settings (requiring approval for every terminal call) to an allowlist, an attacker can execute arbitrary command execution outside of the allowlist without user approval. An attacker can trigger this vulnerability if chained with indirect prompt injection. This is fixed in version 1.3.
