This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is possible because core wp_filter_kses leaves the submitted markup inert, but the plugin's subsequent regex fallback consumes closing quotes of allowed attribute values containing 'bdt-', promoting previously inert bytes — such as event handlers like onfocus — into real HTML attributes that are then written to the database and rendered without further sanitization.","publishedAt":"2026-10-28T06:45:15.943Z","updatedAt":"2026-10-29T01:41:52.430Z","severity":{"score":7.2,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["bdthemes Prime Slider – Hero Slider, Carousel, WooCommerce & Post Slider Elementor Addons"],"affected":[{"vendor":"bdthemes","product":"Prime Slider – Hero Slider, Carousel, WooCommerce & Post Slider Elementor Addons","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"4.7.2","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/918dd473-dbe7-4352-95e9-3f705b09a4f2?source=cve","https://plugins.trac.wordpress.org/browser/bdthemes-prime-slider-lite/tags/4.7.2/includes/class-content-guard.php#L329","https://plugins.trac.wordpress.org/browser/bdthemes-prime-slider-lite/tags/4.7.2/includes/class-content-guard.php#L292","https://plugins.trac.wordpress.org/browser/bdthemes-prime-slider-lite/tags/4.7.2/includes/class-content-guard.php#L128","https://plugins.trac.wordpress.org/browser/bdthemes-prime-slider-lite/tags/4.7.2/includes/class-content-guard.php#L59","https://plugins.trac.wordpress.org/browser/bdthemes-prime-slider-lite/tags/4.7.2/loader.php#L133","https://plugins.trac.wordpress.org/changeset/3752580/bdthemes-prime-slider-lite/trunk/includes/class-content-guard.php"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:10:33.477Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/111xxx/CVE-2026-111111.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-111111","state":"PUBLISHED","datePublished":"2026-10-28T06:45:15.943Z","dateUpdated":"2026-10-29T01:41:52.430Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-10-15T15:58:56.096Z"},"containers":{"cna":{"title":"Prime Slider <= 4.7.2 - Unauthenticated Stored Cross-Site Scripting via Comment Content via Content_Guard Regex Quote-Escape","descriptions":[{"lang":"en","value":"The Prime Slider – Hero Slider, Carousel, WooCommerce & Post Slider Elementor Addons plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'comment' parameter in all versions up to, and including, 4.7.2 due to insufficient input sanitization and output escaping.
