{"cve":"CVE-2025-54073","nvd":{"published":"2025-07-18T16:15:30.350","modified":"2026-06-17T09:39:22.260","status":"Deferred","description":"mcp-package-docs is an MCP (Model Context Protocol) server that provides LLMs with efficient access to package documentation across multiple programming languages and language server protocol (LSP) capabilities. A command injection vulnerability exists in the `mcp-package-docs` MCP Server prior to the fix in commit cb4ad49615275379fd6f2f1cf1ec4731eec56eb9. The vulnerability is caused by the unsanitized use of input parameters within a call to `child_process.exec`, enabling an attacker to inject arbitrary system commands. Successful exploitation can lead to remote code execution under the server process's privileges. The server constructs and executes shell commands using unvalidated user input directly within command-line strings. This introduces the possibility of shell metacharacter injection (`|`, `>`, `&&`, etc.). Commit cb4ad49615275379fd6f2f1cf1ec4731eec56eb9 in version 0.1.27 contains a fix for the issue, but upgrading to 0.1.28 is recommended.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","score":7.5},"cwes":["CWE-77"],"references":["https://equixly.com/blog/2025/03/29/mcp-server-new-security-nightmare","https://github.com/advisories/GHSA-3q26-f695-pp76","https://github.com/advisories/GHSA-5w57-2ccq-8w95","https://github.com/advisories/GHSA-gjv4-ghm7-q58q","https://github.com/sammcj/mcp-package-docs/commit/cb4ad49615275379fd6f2f1cf1ec4731eec56eb9"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:05:46.678065081+00:00"},"epss":{"cve":"CVE-2025-54073","score":0.11291,"percentile":0.95974,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-vf9j-h32g-2764","url":"https://osv.dev/vulnerability/GHSA-vf9j-h32g-2764","summary":"mcp-package-docs vulnerable to command injection in several tools","modified":"2026-02-04T03:58:27.664964Z","packages":[{"ecosystem":"npm","name":"mcp-package-docs","purl":"pkg:npm/mcp-package-docs","ranges":["<0.1.28"],"fixed":["0.1.28"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
