{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/66506?format=json","vulnerability_id":"VCID-wtrx-ye2y-d7gx","summary":"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.","aliases":[{"alias":"CVE-2026-30624"}],"fixed_packages":[],"affected_packages":[],"references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2026-30624","reference_id":"","reference_type":"","scores":[{"value":"0.00323","scoring_system":"epss","scoring_elements":"0.55747","published_at":"2026-06-11T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-30624"},{"reference_url":"https://www.ox.security/blog/mcp-supply-chain-advisory-rce-vulnerabilities-across-the-ai-ecosystem/","reference_id":"mcp-supply-chain-advisory-rce-vulnerabilities-across-the-ai-ecosystem","reference_type":"","scores":[{"value":"8.6","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:Y/T:P/P:M/B:A/M:M/D:T/2026-04-15T18:02:09Z/"}],"url":"https://www.ox.security/blog/mcp-supply-chain-advisory-rce-vulnerabilities-across-the-ai-ecosystem/"}],"weaknesses":[],"exploits":[],"severity_range_score":"8.6 - 8.6","exploitability":null,"weighted_severity":null,"risk_score":null,"resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-wtrx-ye2y-d7gx"}
