Upgrade github.com/siyuan-note/siyuan/kernel/api to version 3.7.0-beta.1 or higher.
Overview
Affected versions of this package are vulnerable to Insecure Default Initialization of Resource via the renderSnippet process. An attacker can execute arbitrary JavaScript code and potentially achieve remote code execution by injecting a crafted CSS snippet containing a </style> tag followed by malicious HTML or JavaScript payloads, which are then interpreted by the renderer. This can lead to code execution on Electron desktop builds where nodeIntegration is enabled, allowing access to Node.js APIs. The attack can be triggered automatically when the application loads or refreshes snippets, without user interaction, and can propagate to all devices syncing the same workspace.
