Critical Cursor Flaws Could Let Prompt Injection Escape Sandbox and Run Commands
Cato AI Labs discovered two critical flaws in Cursor, an AI code editor, tracked as CVE-2026-50548 and CVE-2026-50549, that could allow prompt injection attacks to bypass sandbox protections and execute arbitrary commands on a developer's machine. The vulnerabilities, collectively named DuneSlide, require no user interaction or approval and carry severity ratings of 9.8 and 9.3 respectively. The flaws expose developers to direct command execution through seemingly benign prompts.
Why it matters: If you use Cursor for development, patch immediately; unpatched systems can have arbitrary code executed through prompt injection without any user confirmation.

Critical Cursor Flaws Could Let Prompt Injection Escape Sandbox and Run Commands
Two flaws in Cursor, an artificial intelligence (AI) code editor tracked as CVE-2026-50548 and CVE-2026-50549, allow prompt injection attacks to escape the editor's sandbox and execute arbitrary commands on a developer's machine. Cato AI Labs identified the pair and named them DuneSlide, both rated critical with severity scores of 9.8 and 9.3. No user interaction is required to trigger the exploits.
Why it matters: Developers using Cursor face direct code execution risk from crafted prompts in seemingly ordinary code files or suggestions, requiring immediate patching or removal of the editor until fixes are available.
