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 under the newer CVSS 4.0 scale). The fix is already out. Both bugs are patched in Cursor 3.0, released April 2, and every version before 3.0 is affected. Cursor's maker says more than half the Fortune 500 use the tool, so if you run it, update now. What the sandbox was for, and how it broke Starting in the 2.x line, Cursor runs the terminal commands its AI agent issues inside a sandbox by default: a locked box that limits what those commands can touch, so a stray instruction cannot wreck the machine. DuneSlide is about getting out of that box. The way in is prompt injection . The attacke...

Read more blogs around threat intelligence and adversary research: https://atos.net/en/lp/cybershield  Summary Atos Researchers identified a new variant of the popular ClickFix technique, where attackers convince the user to execute a malicious command on their own device through the Win + R shortcut. In this variation, a “net use” command is used to map a network drive from an external server, after which a “.cmd” batch file hosted on that drive is executed. Script downloads a ZIP archive, unpacks it, and executes the legitimate WorkFlowy application with modified, malicious logic hidden inside “.asar” archive. This acts as...
