CVE-2026-72776

Summary

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.
