CVE-2026-90619Public exploitNetwork attack vector

Unauthenticated code execution via Python execute endpoint

Published Sep 14, 2026 · Updated Sep 14, 2026

OS command injection in 0x4m4 HexStrike AI through d689933ff579d839c676c82b231f8e98326c5f04 allows remote attackers to execute Python code. The unauthenticated /api/python/execute handler writes the supplied code or script value to a Python file and launches that file with the server interpreter. Network reachability to the API is sufficient; code runs with the privileges of the HexStrike server process.
