WordPress 插件"Premium Packages – Sell Digital Products Securely"在所有 7.2.8 及更早版本中存在存储型跨站脚本（Stored XSS）漏洞。该漏洞源于对"note"参数的输入过滤不足以及输出转义缺失。这使得拥有订阅者级别或更高权限的已认证攻击者，能够在页面中注入任意 Web 脚本；当任何用户访问被注入的页面时，这些脚本即会被执行。 该漏洞之所以能绕过基于标签的过滤机制，是因为攻击载荷被存储为十六进制转义序列（例如： ），而 函数无法将其清除。该序列仅

Vulnerability Title
Premium Packages <= 7.2.8 - Authenticated (Subscriber+) Stored Cross-Site Scripting via Order Notes
Source: CVE Program / CVE List V5
Vulnerability Description
The Premium Packages – Sell Digital Products Securely plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'note' parameter in all versions up to, and including, 7.2.8 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The exploit bypasses tag-based filtering because the payload is stored as a hex-escaped sequence (e.g., \x3cimg onerror=...\x3e) that sanitize_textarea_field does not strip, and is only decoded back into a live HTML tag by stripcslashes() during admin rendering — after all sanitization has occurred.
