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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":35,"depthScoreParts":{"impact":35.2,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
