Alert meAnalysisAIv1 – Mar 12, 2026
Stored XSS in LobeChat's Mermaid artifact renderer prior to version 2.0.0-next.180 enables attackers to execute arbitrary JavaScript, which can be escalated to remote code execution through the exposed electronAPI IPC bridge to run system commands. This affects users of the open source chat platform running vulnerable versions, requiring local interaction and high privileges to exploit but resulting in full system compromise. No patch is currently available.
