The function uses Python's exec() to execute user-supplied scripts but fails to restrict the __builtins__ dictionary in the globals parameter. When __builtins__ is not explicitly defined, Python automatically provides access to all built-in functions including __import__, exec, eval, and open. This allows an attacker to execute arbitrary Python code with full system privileges, leading to complete system compromise. The vulnerability can be exploited by submitting a malicious script to the run_script tool, requiring no authentication or special privileges.","epss":null,"exploits":[{"kind":"exploit","source":"cve@mitre.org","url":"https://github.com/reading-plus-ai/mcp-server-data-exploration/issues/12"}],"kev":null,"metrics":[{"score":6.5,"severity":"medium","source":"NVD: 134c704f-9b21-4f2e-91b3-4a467353bcc0","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"}],"modifiedAt":1794075000200,"publishedAt":1763482545833,"references":[{"source":"cve@mitre.org","tags":["Exploit","Issue Tracking","Third Party Advisory"],"url":"https://github.com/reading-plus-ai/mcp-server-data-exploration/issues/12"}],"remediation":[],"revision":"0dfbfd1fae2d66c1749c45e9b23ff44c4fca3a931f074175930a9a37f9cffeb3","sources":[{"modifiedAt":1794075000200,"name":"NVD","retrievedAt":1794075445405,"url":"https://nvd.nist.gov/vuln/detail/CVE-2025-63603"}],"ssvc":{"assessedAt":1763485480785,"automatable":"yes","exploitation":"poc","source":"NVD SSVC: 134c704f-9b21-4f2e-91b3-4a467353bcc0","technicalImpact":"total"},"status":"published","title":"CVE-2025-63603","updatedAt":1794075445405}
