{"id":"CVE-2026-4496","state":"PUBLISHED","title":"sigmade Git-MCP-Server gitUtils.ts child_process.exec os command injection","description":"A vulnerability was found in sigmade Git-MCP-Server up to 785aa159f262a02d5791a5d8a8e13c507ac42880. Affected by this vulnerability is the function child_process.exec of the file src/gitUtils.ts of the component show_merge_diff/quick_merge_summary/show_file_diff. The manipulation results in os command injection. The attack must be initiated from a local position. The exploit has been made public and could be used. This product operates on a rolling release basis, ensuring continuous delivery. Consequently, there are no version details for either affected or updated releases. It is advisable to implement a patch to correct this issue. The vendor was contacted early about this disclosure but did not respond in any way.","publishedAt":"2026-03-20T18:32:13.041Z","updatedAt":"2026-03-25T13:59:02.878Z","severity":{"score":4.8,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P","source":"VulDB"},"assigner":"VulDB","products":["sigmade Git-MCP-Server"],"affected":[{"vendor":"sigmade","product":"Git-MCP-Server","versions":[{"version":"785aa159f262a02d5791a5d8a8e13c507ac42880","status":"affected"}],"modules":["show_merge_diff/quick_merge_summary/show_file_diff"]}],"references":["https://vuldb.com/?id.352045","https://vuldb.com/?ctiid.352045","https://vuldb.com/?submit.773796","https://github.com/sigmade/Git-MCP-Server/issues/1","https://github.com/user-attachments/files/24855745/Git-MCP-Server.bug.pdf","https://github.com/sigmade/Git-MCP-Server/pull/2","https://github.com/sigmade/Git-MCP-Server/"],"weaknesses":["CWE-78","CWE-77"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/4xxx/CVE-2026-4496.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-4496","state":"PUBLISHED","datePublished":"2026-03-20T18:32:13.041Z","dateUpdated":"2026-03-25T13:59:02.878Z","assignerShortName":"VulDB","assignerOrgId":"1af790b2-7ee1-4545-860a-a788eba489b5","dateReserved":"2026-03-20T09:15:25.741Z"},"containers":{"cna":{"title":"sigmade Git-MCP-Server gitUtils.ts child_process.exec os command injection","descriptions":[{"lang":"en","value":"A vulnerability was found in sigmade Git-MCP-Server up to 785aa159f262a02d5791a5d8a8e13c507ac42880.
