It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires no authentication.

Vulnerability Overview
The 多合一搜索自动推送管理插件-支持Baidu/Google/Bing/IndexNow/Yandex/头条 plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 4.2.5. This is due to missing nonce validation on the wp_ajax_wb_baidu_push_url() function called via an AJAX action. This makes it possible for unauthenticated attackers to perform several actions such as modifying the plugins settings and clearing logs, granted they can trick a site administrator into performing an action such as clicking on a link.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site.
CWE-352: Cross-Site Request Forgery (CSRF)
多合一搜索自动推送管理插件-支持Baidu/Google/Bing/IndexNow/Yandex/头条 <= 4.2.5 carries this weakness at wp_ajax_wb_baidu_push_url(), and reaching it takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.
An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For 多合一搜索自动推送管理插件-支持Baidu/Google/Bing/IndexNow/Yandex/头条 the fix is 4.2.6: builds <= 4.2.5 are affected, anything from 4.2.6 onward is not.
Remediation
Update to version 4.2.6, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to 多合一搜索自动推送管理插件-支持Baidu/Google/Bing/IndexNow/Yandex/头条: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: 多合一搜索自动推送管理插件-支持Baidu/Google/Bing/IndexNow/Yandex/头条 4.2.6 closes this, and updating the plugin is the step that ends it.
