{"id":"CVE-2025-66401","aliases":["GHSA-27m7-ffhq-jqrm"],"url":"https://o3.security/vulnerability/CVE-2025-66401","summary":"MCP Watch has a Critical Command Injection in cloneRepo allows Remote Code Execution (RCE) via malicious URL","details":"MCP Watch is a comprehensive security scanner for Model Context Protocol (MCP) servers. In 0.1.2 and earlier, the MCPScanner class contains a critical Command Injection vulnerability in the cloneRepo method. The application passes the user-supplied githubUrl argument directly to a system shell via execSync without sanitization. This allows an attacker to execute arbitrary commands on the host machine by appending shell metacharacters to the URL.","published":"2025-12-01T22:43:26.639Z","modified":"2026-07-15T01:49:16.369685665Z","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"mcp-watch","fixedVersion":null}],"fix":{"url":"https://github.com/kapilduraphe/mcp-watch/commit/e7da78c5b4b960f8b66c254059ad9ebc544a91a6","label":"kapilduraphe/mcp-watch@e7da78c"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/66xxx/CVE-2025-66401.json"},{"type":"ADVISORY","url":"https://github.com/kapilduraphe/mcp-watch/security/advisories/GHSA-27m7-ffhq-jqrm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-66401"},{"type":"FIX","url":"https://github.com/kapilduraphe/mcp-watch/commit/e7da78c5b4b960f8b66c254059ad9ebc544a91a6"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:16.369685665Z"}}
