CVE-2026-15010— bbp style pack <= 6.4.5 - Authenticated (Subscriber+) Stored Cross-Site Scripting via Topic Form Additional Fields

bbp style pack <= 6.4.5 - Authenticated (Subscriber+) Stored Cross-Site Scripting via Topic Form Additional Fields

The bbp Style Pack plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 6.4.5 via the Topic Form Additional Fields feature. This is due to insufficient input sanitization in bsp_topic_fields_form_save() (which writes $_POST['bsp_topic_fields_label{n}'] directly to post meta via update_post_meta() with no filtering) and missing output escaping in bsp_topic_content_append_topic_fields() (which concatenates the stored meta value into an HTML <span> and echoes it via apply_filters/echo without esc_html()). This makes it possible for authenticated attackers, with Subscriber-level access and above (who have bbPress topic-creation privileges), to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page, including unauthenticated visitors.

在Web页面生成时对输入的转义处理不恰当(跨站脚本)

WordPress bbp style pack 跨站脚本漏洞

WordPress bbp style pack是WordPress基金会的一款文档管理与展示扩展插件。 WordPress bbp style pack 6.4.5及之前版本存在跨站脚本漏洞，该漏洞源于Topic Form Additional Fields功能存在存储型跨站脚本，由于bsp_topic_fields_form_save()函数中对输入清理不足且bsp_topic_content_append_topic_fields()函数中缺少输出转义，可能导致认证攻击者注入任意Web脚本。
