CVE-2025-66562Network attack vector

System command execution via unsafe ECharts evaluation

Published Dec 5, 2025 · Updated Dec 5, 2025

Code injection in AI-QL TUUI before 1.3.4 allows remote attackers to execute system commands when a user views malicious Markdown. MarkdownCard.vue evaluates ECharts code-block content as JavaScript under an unsafe-eval policy, while mainApi.invoke exposes IPC values to process spawning. No account is required, but a user must display the crafted message; successful exploitation runs commands with the desktop client's privileges.
