WordPress 的 Flamingo 插件存在授权绕过漏洞，影响 2.6.2 及之前所有版本。该漏洞源于插件未能正确验证用户是否具有执行相应操作的权限。因此，拥有贡献者（contributor）及以上权限的已认证攻击者可以利用此漏洞枚举分类术语（taxonomy terms），包括从 Contact Form 7 表单标题中派生的频道名称（这些名称可能暴露内部表单用途、部门名称或工作流标识符），以及每个频道的提交数量和联系标签名称。该插件的 过滤器虽然限制了用户访问 Flamingo 的管理界面，但这一限制并未

Vulnerability Title
Flamingo <= 2.6.2 - Authenticated (Contributor+) Missing Authorization to Unauthorized Tag Information Disclosure via wp.getTerms and ajax-tag-search
Source: CVE Program / CVE List V5
Vulnerability Description
The Flamingo plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.6.2. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with contributor-level access and above, to enumerate taxonomy terms including channel names derived from Contact Form 7 form titles that may reveal internal form purposes, department names, or workflow identifiers, as well as submission counts per channel and contact tag names. The plugin's flamingo_map_meta_cap() filter restricts access to Flamingo's admin UI but does not extend to WordPress core APIs such as XML-RPC wp.getTerms and admin-ajax ajax-tag-search.
