CVE-2026-85694Public exploitNetwork attack vector

Remote code execution via unsafe model-output eval

Published Sep 4, 2026 · Updated Sep 8, 2026

Code injection in LaVague 0.2.35 and earlier allows remote attackers to execute arbitrary Python code through malicious web-page content. PythonFromMarkdownExtractor.extract_as_object extracts a Python block from model output and passes it directly to eval without restricting expressions or built-ins. Exploitation requires an agent workflow to process attacker-influenced page content, after which the code runs on the operator host without per-action review.
