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 BuddyForms 插件在所有版本（包括 2.10.5 及更早版本）中存在权限提升漏洞。该漏洞可通过 参数利用“表单类型混淆”攻击进行利用。 漏洞成因如下：面向公众的前端提交处理函数 仅依据目标表单的 标志来授权未登录用户的提交，同时却无条件信任攻击者提供的 参数来决定新创建对象的帖子类型。虽然 2.10.2 版本引入了一项交叉检查机制，但该机制仅适用于已存在的帖子（即 ），在创建新对象时完全被绕过。此外， 监听器 既未包含 能力检查，也缺少表单构建器的 nonce 验证，导致其无条件持久

Vulnerability Title
BuddyForms <= 2.10.5 - Unauthenticated Privilege Escalation to Form-Type Confusion via 'bf_post_type' Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
The BuddyForms plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.10.5 via a form-type confusion attack through the `bf_post_type` parameter. This is due to the public frontend submission handler `buddyforms_form_response_no_ajax()` authorizing logged-out submissions based solely on the target form's `public_submit` flag while independently trusting the attacker-supplied `$_POST['bf_post_type']` to determine the post type of the newly created object — a cross-check introduced in 2.10.2 applies only to existing posts (`post_id != 0`) and is completely bypassed for new-object creation — combined with the `save_post` listener `buddyforms_edit_form_save_meta_box_data()` lacking both a `current_user_can()` capability check and a form-builder nonce, causing it to unconditionally persist attacker-supplied `$_POST['buddyforms_options']` for any newly inserted `buddyforms` CPT post. This makes it possible for unauthenticated attackers to insert a rogue BuddyForms form configuration with an attacker-controlled `new_user_role` value into the live global form registry, then submit a registration through that form to create a new WordPress account with administrator-level privileges and achieve full site takeover. Exploitation requires the WordPress site to have "Anyone can register" enabled and at least one public BuddyForms form attached to a page, both of which are standard BuddyForms deployment configurations.
