{"id":"CVE-2026-15010","state":"PUBLISHED","title":"bbp style pack <= 6.4.5 - Authenticated (Subscriber+) Stored Cross-Site Scripting via Topic Form Additional Fields","description":"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.","publishedAt":"2026-07-11T06:50:33.433Z","updatedAt":"2026-07-13T16:11:39.208Z","severity":{"score":6.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["robin-w bbp style pack"],"affected":[{"vendor":"robin-w","product":"bbp style pack","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"6.4.5","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/f898ab34-2d63-458d-b19b-4e2b6f4a0f3b?source=cve","https://plugins.trac.wordpress.org/browser/bbp-style-pack/tags/6.4.5/includes/functions_topic_fields.php#L146","https://plugins.trac.wordpress.org/browser/bbp-style-pack/tags/6.4.5/includes/functions_topic_fields.php#L235","https://plugins.trac.wordpress.org/changeset?reponame=&old=3601461%40bbp-style-pack&new=3601461%40bbp-style-pack"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/15xxx/CVE-2026-15010.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-15010","state":"PUBLISHED","datePublished":"2026-07-11T06:50:33.433Z","dateUpdated":"2026-07-13T16:11:39.208Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-07-07T21:52:36.970Z"},"containers":{"cna":{"title":"bbp style pack <= 6.4.5 - Authenticated (Subscriber+) Stored Cross-Site Scripting via Topic Form Additional Fields","descriptions":[{"lang":"en","value":"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.
