{"id":"CVE-2026-6108","state":"PUBLISHED","title":"1Panel-dev MaxKB Model Context Protocol Node base_mcp_node.py execute os command injection","description":"A vulnerability was found in 1Panel-dev MaxKB up to 2.6.1. The affected element is the function execute of the file apps/application/flow/step_node/mcp_node/impl/base_mcp_node.py of the component Model Context Protocol Node. Performing a manipulation results in os command injection. The attack is possible to be carried out remotely. The exploit has been made public and could be used. You should upgrade the affected component. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.","publishedAt":"2026-04-12T01:00:19.735Z","updatedAt":"2026-04-14T14:00:16.365Z","severity":{"score":5.3,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:N/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":["1Panel-dev MaxKB"],"affected":[{"vendor":"1Panel-dev","product":"MaxKB","versions":[{"version":"2.6.0","status":"affected"},{"version":"2.6.1","status":"affected"}],"cpes":["cpe:2.3:a:maxkb:maxkb:*:*:*:*:*:*:*:*"],"modules":["Model Context Protocol Node"]}],"references":["https://vuldb.com/vuln/356968","https://vuldb.com/vuln/356968/cti","https://vuldb.com/submit/782279","https://github.com/AnalogyC0de/public_exp/issues/30"],"weaknesses":["CWE-78","CWE-77"],"ingestedAt":"2026-10-29T20:12:49.727Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/6xxx/CVE-2026-6108.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-6108","state":"PUBLISHED","datePublished":"2026-04-12T01:00:19.735Z","dateUpdated":"2026-04-14T14:00:16.365Z","assignerShortName":"VulDB","assignerOrgId":"1af790b2-7ee1-4545-860a-a788eba489b5","dateReserved":"2026-04-11T07:35:04.182Z"},"containers":{"cna":{"title":"1Panel-dev MaxKB Model Context Protocol Node base_mcp_node.py execute os command injection","descriptions":[{"lang":"en","value":"A vulnerability was found in 1Panel-dev MaxKB up to 2.6.1.
