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 Post Views Stats Counter 插件在所有版本（包括 1.1.7 及更早版本）中，由于输入清理和输出转义不足，存在通过 User-Agent 请求头进行存储型跨站脚本攻击（Stored XSS）的漏洞。这使得未经身份验证的攻击者能够向页面中注入任意 Web 脚本，当用户访问被注入的页面时，这些脚本将会执行。该插件唯一的输入过滤机制是一个针对已知机器人特征（例如 'bot'、'spider'、'crawler'）的子串黑名单，攻击者只需构造一个不包含这些字符串的 User-A

Vulnerability Title
Post Views Stats Counter <= 1.1.7 - Unauthenticated Stored Cross-Site Scripting via User-Agent Header
Source: CVE Program / CVE List V5
Vulnerability Description
The Post Views Stats Counter plugin for WordPress is vulnerable to Stored Cross-Site Scripting via User-Agent Header in all versions up to, and including, 1.1.7 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The plugin's only input filter is a substring blacklist for known bot signatures (e.g. 'bot', 'spider', 'crawler'), which can be trivially bypassed by crafting a User-Agent payload that omits those strings.
