CVE-2025-58768Public exploitNetwork attack vector

Command execution via unsanitized Mermaid innerHTML

Published Sep 9, 2025 · Updated Sep 9, 2025

Code injection in ThinkInAIXYZ DeepChat before 0.3.5 allows remote attackers to execute arbitrary commands through crafted Mermaid content. MermaidArtifact.vue assigns attacker-controlled chart content directly to mermaidRef.value.innerHTML, allowing injected JavaScript to call the exposed electron.ipcRenderer interface. A victim must render the crafted chart, after which the IPC bridge can register and start an attacker-specified command as an MCP server process.
