Technical ContextAI · show details
This vulnerability is classified as Server-Side Request Forgery (SSRF) (CWE-918), which allows attackers to make the server perform requests to unintended internal or external resources. Cursor is a code editor built for programming with AI. In versions below 1.3, Mermaid (which is used to render diagrams) allows embedding images which then get rendered by Cursor in the chat box. An attacker can use this to exfiltrate sensitive information to a third-party attacker controlled server through an image fetch after successfully performing a prompt injection. A malicious model (or hallucination/backdoor) might also trigger this exploit at will. This issue requires prompt injection from malicious data (web, image upload, source code) in order to exploit. In that case, it can send sensitive information to an attacker-controlled external server. This is fixed in version 1.3. Affected products include: Anysphere Cursor. Version information: version 1.3..

Executive ViewAI
Organizations using Cursor should be aware of moderate risk from CVE-2025-54132, a server-side request forgery vulnerability rated CVSS 4.4. Users could be tricked into performing unintended actions. Organizations should apply vendor updates when available and monitor for exploitation.
Apply vendor patch. If patching is delayed: implement egress filtering, block metadata endpoints.
