Detailsinfo

A vulnerability was found in robin-w bbp Style Pack Plugin up to 6.4.5. It has been declared as problematic. Affected by this vulnerability is the function bsp_topic_fields_form_save/bsp_topic_content_append_topic_fields of the component Topic Form Additional Fields Feature. The manipulation of the argument bsp_topic_fields_label{n} with an unknown input leads to a cross site scripting vulnerability. The CWE definition for the vulnerability is CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. As an impact it is known to affect integrity. The summary by CVE is:

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.

The advisory is shared at wordfence.com. This vulnerability is known as CVE-2026-15010 since 07/07/2026. The exploitation appears to be easy. The attack can be launched remotely.
