Quick assessment

Affected
Unknown Visualizer
Exploitation

Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Visualizer WordPress 插件在 4.0.7 版本之前存在权限验证不当的问题，未正确限制对图表配置的访问权限。这使得具有“Contributor”（贡献者）及更高角色的用户能够读取网站上任意图表的完整配置信息，即使这些图表已被 Visualizer 插件的前端界面限制其访问权限，用户仍可通过单次请求获取所有图表的配置数据。泄露的配置信息中可能包含图表所连接的远程数据源的用户凭据。
