WordPress 的 WP Photo Album Plus 插件在所有不超过 9.3.03.002 版本的系统中，存在存储型跨站脚本（Stored Cross-Site Scripting）漏洞。该漏洞源于 REQUEST_URI 会话历史中未充分进行输入净化和输出转义，致使未认证的攻击者能够在网页中注入任意 Web 脚本。一旦用户访问被注入的页面，这些脚本便会自动执行。漏洞利用的关键在于： 函数虽然会剥离字面意义上的尖括号（即 和 ），但仍保留 HTML 实体编码；随后， 函数会将这些 HTML 实体静默地转

Vulnerability Title
WP Photo Album Plus <= 9.3.03.002 - Unauthenticated Stored Cross-Site Scripting via REQUEST_URI Session History
Source: CVE Program / CVE List V5
Vulnerability Description
The WP Photo Album Plus plugin for WordPress is vulnerable to Stored Cross-Site Scripting via REQUEST_URI Session History in all versions up to, and including, 9.3.03.002 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 bypass works because esc_url_raw() strips literal angle brackets but retains HTML entities, which wppaEntityDecode() silently converts back to live HTML tags before jQuery('#wppa-modal-container').html() renders them.
