Sandbox bypass flaws in Cursor IDE highlight prompt injection as an RCE vector
Researchers have discovered two vulnerabilities in the widely used Cursor AI-enabled integrated development environment (IDE) that can be exploited through prompt injection to achieve remote code execution (RCE).
AI Summary
Researchers identified two vulnerabilities in Cursor’s AI‑enabled IDE, catalogued as CVE‑2026‑50548 and CVE‑2026‑50549. The flaws enable prompt injection attacks that let an attacker escape the IDE’s command‑execution sandbox. The sandbox is designed to stop the internal AI agent from executing unauthorized actions on the host operating system. By bypassing this protective layer, attackers can achieve remote code execution on the system running Cursor.
