WordPress 的 Bootstrap Shortcodes 插件在 3.4.6 版本之前存在存储型跨站脚本（XSS）漏洞。该漏洞源于 短代码的 属性。位于 中的 短代码处理函数会将 属性值输出到未加引号的 HTML 属性中。虽然调用了 函数，但该函数并未对空格字符进行编码，因此若输入值中包含空格，该空格会提前终止当前属性，导致后续文本被解析为额外的 HTML 属性，其中包括 JavaScript 事件处理器。这使得拥有“投稿者”（Contributor）权限或更高权限的已认证攻击者能够注入任意 Web 脚本，

Vulnerability Title
N/A
Source: CVE Program / CVE List V5
Vulnerability Description
The Bootstrap Shortcodes plugin for WordPress before 3.4.6 is vulnerable to stored XSS via the id attribute of the [bs_tcontent] shortcode. The bs_tcontent() shortcode handler in inc/bs_tabs.php emits the id attribute value into an unquoted HTML attribute. esc_attr() is applied, but it does not encode space characters, so a space in the supplied value terminates the attribute and any following text is parsed as additional HTML attributes, including JavaScript event handlers. This allows authenticated attackers with Contributor-level access and above to inject arbitrary web script that executes in the browser of any user who views the page and interacts with the injected element.
