CyberRota Analysis

AI-Generated

Versions of SiYuan prior to v3.7.4 are vulnerable to stored cross-site scripting due to improper validation of table column width values, enabling attackers to inject malicious payloads via the setAttrViewColWidth API. This vulnerability allows for the execution of arbitrary code in the Electron renderer, particularly when Node integration is enabled, posing a significant risk to user data and application integrity. Organizations using affected versions should prioritize immediate updates to mitigate this critical security threat.

Original NVD Description

SiYuan versions before v3.7.4 fail to validate or escape table column width values, allowing stored cross-site scripting injection into style attributes. Attackers can inject malicious payloads through the setAttrViewColWidth API that break out of style attributes and inject event handlers on every table cell, executing arbitrary code in the Electron renderer with Node integration enabled.
