{"id":"CVE-2026-72776","summary":"AgenticSeek Unauthenticated RCE via /query API Endpoint","details":"AgenticSeek (commit fc242c7) contains an unauthenticated remote code execution vulnerability that allows any network-adjacent attacker to execute arbitrary commands by submitting crafted queries to the unprotected POST /query API endpoint bound to 0.0.0.0:7777 with wildcard CORS. Attackers can send unauthenticated HTTP requests that cause the autonomous agent to generate and execute shell commands through BashInterpreter using subprocess.Popen with shell=True and safety=False, bypassing the incomplete command blocklist to achieve full host-level code execution.","modified":"2026-10-08T02:51:55.293917911Z","published":"2026-08-13T21:14:18.395Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72776.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-306"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72776.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72776"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/agenticseek-unauthenticated-rce-via-query-api-endpoint"},{"type":"REPORT","url":"https://github.com/Fosowl/agenticSeek/issues/520"},{"type":"FIX","url":"https://github.com/Fosowl/agenticSeek/pull/534/changes/f1eb2cfc721f8a21dd16a8b048a9ca89f3259f6f"},{"type":"PACKAGE","url":"https://github.com/Fosowl/agenticSeek"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/Fosowl/agenticSeek","events":[{"introduced":"0"},{"fixed":"f1eb2cfc721f8a21dd16a8b048a9ca89f3259f6f"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72776.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
