CVE-2026-85672Network attack vector

Command execution via unsanitized document URL extension

Published Sep 4, 2026 · Updated Sep 8, 2026

OS command injection in Omni AI Zerox 1.1.20 and earlier allows remote attackers to execute arbitrary commands through a document URL. The file downloader derives a temporary extension from the URL and interpolates it without sanitization into shell commands that invoke Poppler utilities. The application must process an attacker-controlled document URL; injected commands run with the privileges of the hosting process before document conversion begins.
