If a sensitive editor file like .vscode\/settings.json does not exist in the workspace, an attacker can create a new one, bypassing the need for approval. By chaining a prompt injection vulnerability, the attacker can hijack the context, write to the settings file, and trigger remote code execution on the victim&#8217;s system without user approval.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-697089556\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>The below pseudocode demonstrates how the vulnerability might be exploited. It involves creating a new .vscode\/settings.json file and writing malicious code into it:<\/p>\n<pre><code class=\"\" data-line=\"\">if (!fileExists(&#039;.vscode\/settings.json&#039;)) {\ncreateFile(&#039;.vscode\/settings.json&#039;);\nwriteToFile(&#039;.vscode\/settings.json&#039;, malicious_code);\n}\nexecute(&#039;.vscode\/settings.json&#039;);<\/code><\/pre>\n<p>In this example, `malicious_code` represents the payload an attacker would use to gain control over the victim&#8217;s system.<\/p>\n<p><strong>Mitigation<\/strong><\/p>\n<p>Users are advised to apply the vendor patch by upgrading to Cursor version 1.3.9 or later. In the absence of a patch, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as a temporary mitigation measure.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview The CVE-2025-54130 vulnerability refers to a design flaw in the AI-based code editor &#8211; Cursor.
