{"id":"CVE-2024-48919","state":"PUBLISHED","title":"RCE via Prompt Injection Into Cursor's Terminal Cmd-K","description":"Cursor is a code editor built for programming with AI. Prior to Sep 27, 2024, if a user generated a terminal command via Cursor's Terminal Cmd-K/Ctrl-K feature and if the user explicitly imported a malicious web page into the Terminal Cmd-K prompt, an attacker with control over the referenced web page could have a significant chance of influencing a language model to output arbitrary commands for execution in the user's terminal. This scenario would require the user explicitly opt-in to including the contents of a compromised webpage, and it would require that the attacker display prompt injection text in the the contents of the compromised webpage.\n\nA server-side patch to not stream back newlines or control characters was released on September 27, 2024, within two hours of the issue being reported. Additionally, Cursor 0.42 includes client-side mitigations to prevent any newline or control character from being streamed into the terminal directly. It also contains a new setting, `\"cursor.terminal.usePreviewBox\"`, which, if set to true, streams the response into a preview box whose contents then have to be manually accepted before being inserted into the terminal. This setting is useful if you're working in a shell environment where commands can be executed without pressing enter or any control character. The patch has been applied server-side, so no additional action is needed, even on older versions of Cursor. Separately, Cursor's maintainers also recommend, as best practice, to only include trusted pieces of context in prompts.","publishedAt":"2024-10-22T20:58:21.962Z","updatedAt":"2024-10-23T14:49:26.530Z","severity":{"score":9.2,"label":"Critical","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["getcursor cursor"],"affected":[{"vendor":"getcursor","product":"cursor","versions":[{"version":"< 0.42","status":"affected"}]}],"references":["https://github.com/getcursor/cursor/security/advisories/GHSA-rmj9-23rg-gr67"],"weaknesses":["CWE-20"],"ingestedAt":"2026-10-29T20:07:56.516Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2024/48xxx/CVE-2024-48919.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2024-48919","state":"PUBLISHED","datePublished":"2024-10-22T20:58:21.962Z","dateUpdated":"2024-10-23T14:49:26.530Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2024-10-09T22:06:46.172Z"},"containers":{"cna":{"title":"RCE via Prompt Injection Into Cursor's Terminal Cmd-K","descriptions":[{"lang":"en","value":"Cursor is a code editor built for programming with AI.
