Cursor allows writing in-workspace files with no user approval in versions below 1.3.9, If the file is a dotfile, editing it requires approval but creating a new one doesn't. Hence, if sensitive MCP files, such as the .cursor/mcp.json file don't already exist in the workspace, an attacker can chain a indirect prompt injection vulnerability to hijack the context to write to the settings file and trigger RCE on the victim without user approval. This is fixed in version 1.3.9."}]}, "problemtype": {"problemtype_data": [{"description": [{"lang": "en", "value": "CWE-78"}, {"lang": "en", "value": "CWE-829"}]}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2025-54135", "ASSIGNER": "security-advisories@github.com"}}, "impact": {}, "publishedDate": "2025-08-05T01:15Z", "configurations": {"nodes": [], "CVE_data_version": "4.0"}, "lastModifiedDate": "2025-08-05T01:15Z"}
