{"id":"CVE-2026-4076","state":"PUBLISHED","title":"Slider Bootstrap Carousel <= 1.0.7 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes","description":"The Slider Bootstrap Carousel plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'category' and 'template' shortcode attributes in all versions up to and including 1.0.7. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes. The plugin uses extract() on shortcode_atts() to parse attributes, then directly outputs the $category variable into multiple HTML attributes (id, data-target, href) on lines 38, 47, 109, and 113 without applying esc_attr(). Similarly, the $template attribute flows into a class attribute on line 93 without escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.","publishedAt":"2026-04-22T07:45:32.908Z","updatedAt":"2026-04-22T12:15:44.853Z","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":["felipermendes Slider Bootstrap Carousel"],"affected":[{"vendor":"felipermendes","product":"Slider Bootstrap Carousel","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.0.7","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/26fe0b7b-dbf8-467f-b5e2-86a858eeaf89?source=cve","https://plugins.trac.wordpress.org/browser/slider-bootstrap-carousel/trunk/includes/sbc-shortcode.php#L38","https://plugins.trac.wordpress.org/browser/slider-bootstrap-carousel/tags/1.0.7/includes/sbc-shortcode.php#L38","https://plugins.trac.wordpress.org/browser/slider-bootstrap-carousel/trunk/includes/sbc-shortcode.php#L7","https://plugins.trac.wordpress.org/browser/slider-bootstrap-carousel/tags/1.0.7/includes/sbc-shortcode.php#L7","https://plugins.trac.wordpress.org/browser/slider-bootstrap-carousel/trunk/includes/sbc-shortcode.php#L47","https://plugins.trac.wordpress.org/browser/slider-bootstrap-carousel/tags/1.0.7/includes/sbc-shortcode.php#L47","https://plugins.trac.wordpress.org/browser/slider-bootstrap-carousel/trunk/includes/sbc-shortcode.php#L93","https://plugins.trac.wordpress.org/browser/slider-bootstrap-carousel/tags/1.0.7/includes/sbc-shortcode.php#L93","https://plugins.trac.wordpress.org/browser/slider-bootstrap-carousel/trunk/includes/sbc-shortcode.php#L109","https://plugins.trac.wordpress.org/browser/slider-bootstrap-carousel/tags/1.0.7/includes/sbc-shortcode.php#L109","https://plugins.trac.wordpress.org/browser/slider-bootstrap-carousel/trunk/includes/sbc-shortcode.php#L113","https://plugins.trac.wordpress.org/browser/slider-bootstrap-carousel/tags/1.0.7/includes/sbc-shortcode.php#L113"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/4xxx/CVE-2026-4076.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-4076","state":"PUBLISHED","datePublished":"2026-04-22T07:45:32.908Z","dateUpdated":"2026-04-22T12:15:44.853Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-12T19:57:39.259Z"},"containers":{"cna":{"title":"Slider Bootstrap Carousel <= 1.0.7 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes","descriptions":[{"lang":"en","value":"The Slider Bootstrap Carousel plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'category' and 'template' shortcode attributes in all versions up to and including 1.0.7.
