CVE-2025-49150 Information

Description

Cursor is a code editor built for programming with AI. Prior to 0.51.0 by default the setting json.schemaDownload.enable was set to True. This means that by writing a JSON file an attacker can trigger an arbitrary HTTP GET request that does not require user confirmation. Since the Cursor Agent can edit JSON files this means a malicious agent for example after a prompt injection attack already succeeded could trigger a GET request to an attacker controlled URL potentially exfiltrating other data the agent may have access to. This vulnerability is fixed in 0.51.0.
