Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

WordPress 的 DesignSetGo 插件在所有 2.11.0 及更早版本中，因输入清理和输出转义不足，存在通过"tagName"参数引发的存储型跨站脚本（Stored XSS）漏洞。该漏洞允许拥有“贡献者”及以上权限的已认证攻击者，在页面中注入任意 Web 脚本；一旦用户访问被注入的页面，这些脚本便会执行。 成功利用该漏洞需要管理员执行插件的区块转换迁移操作（即在停用插件时运行"Scan & Convert Blocks"功能），该操作会触发存在漏洞的 build_group_block() 函数，从而

Vulnerability Title
DesignSetGo <= 2.11.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'tagName' Block Attribute
Source: CVE Program / CVE List V5
Vulnerability Description
The DesignSetGo plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'tagName' parameter in all versions up to, and including, 2.11.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Successful exploitation requires an administrator to run the plugin's block-conversion migration ("Scan & Convert Blocks" during deactivation), which triggers the vulnerable build_group_block() function and promotes the dormant payload from a block delimiter comment into live post_content HTML. Successful exploitation additionally requires an action by an administrator — the attacker cannot trigger the vulnerability on their own.
