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

The Hacker News

Researchers at Cato AI Labs have identified two serious vulnerabilities in Cursor, an AI code editor. These flaws, named DuneSlide and tracked as CVE-2026-50548 and CVE-2026-50549, could allow an attacker to bypass the editor's safety sandbox using a seemingly harmless prompt. This means that any command could potentially be executed on a developer's computer without requiring any user interaction, such as clicks or approvals. With a severity rating of 9.8 out of 10, these vulnerabilities pose a significant risk to developers using Cursor. It is crucial for users to remain vigilant and consider the implications of these flaws on their systems and data security.
