{"id":"CVE-2026-30624","details":"Agent Zero 0.9.8 contains a remote code execution vulnerability in its External MCP Servers configuration feature. The application allows users to define MCP servers using a JSON configuration containing arbitrary command and args values. These values are executed by the application when the configuration is applied without sufficient validation or restriction. An attacker may supply a malicious MCP configuration to execute arbitrary operating system commands, potentially resulting in remote code execution with the privileges of the Agent Zero process.","modified":"2026-07-15T01:49:14.824488730Z","published":"2026-04-15T00:00:00Z","database_specific":{"cna_assigner":"mitre","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/30xxx/CVE-2026-30624.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/30xxx/CVE-2026-30624.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-30624"},{"type":"ADVISORY","url":"https://www.ox.security/blog/mcp-supply-chain-advisory-rce-vulnerabilities-across-the-ai-ecosystem/"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/agent0ai/agent-zero","events":[{"introduced":"0160fd06ce2e60b3715875155c194e4f10b5c8ef"},{"last_affected":"0160fd06ce2e60b3715875155c194e4f10b5c8ef"}],"database_specific":{"extracted_events":[{"introduced":"0.9.8-NA"},{"last_affected":"0.9.8-NA"}],"source":"CPE_STRING","cpe":"cpe:2.3:a:agent-zero:agent-zero:0.9.8:-:*:*:*:*:*:*"}}],"versions":["0.9.8-NA","v0.9.8-pre"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-30624.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H"}]}
