Critical Cursor IDE RCE Vulnerabilities Enable Prompt Injection in Zero-Click

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). The two flaws, tracked as CVE-2026-50548 and CVE-2026-50549, allow attackers to break out of Cursor’s command execution sandbox, the protective layer that’s supposed to prevent the internal AI agent from performing rogue actions on the …

Critical Cursor Flaws Could Let Prompt Injection Escape Sandbox and Run Commands

Two flaws in Cursor, an AI code editor, could let a single, ordinary-looking prompt break out of the editor's safety sandbox and run any command on a developer's computer. There is no click to fall for and no approval box to ignore. Cato AI Labs found the pair and named them DuneSlide. They are tracked as CVE-2026-50548 and CVE-2026-50549, both rated 9.8 out of 10 (or 9.3
