CyberRota Analysis

AI-Generated

Versions of SiYuan prior to 3.7.4 are vulnerable due to inadequate enforcement of publish-access checks in specific API endpoints, allowing unauthorized retrieval of sensitive block attributes from protected documents. This could lead to exposure of critical information such as names, aliases, memos, and custom fields. Organizations using affected versions should prioritize patching to mitigate potential data leaks.
