{"id":"CVE-2026-6048","state":"PUBLISHED","title":"Flipbox Addon for Elementor <= 2.1.1 - Authenticated (Author+) Stored Cross-Site Scripting via Custom Attributes","description":"The Flipbox Addon for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Flipbox widget's button URL `custom_attributes` field in all versions up to, and including, 2.1.1 due to insufficient validation of custom attribute names. Specifically, the plugin uses `esc_html()` on the attribute name which does not prevent event handler attributes (e.g., `onmouseover`, `onclick`). This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.","publishedAt":"2026-04-18T03:37:05.751Z","updatedAt":"2026-04-20T13:46:08.081Z","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":["dragwyb Flipbox Addon for Elementor"],"affected":[{"vendor":"dragwyb","product":"Flipbox Addon for Elementor","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.0.8","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/faa6ad51-7b3b-4fe1-95fa-e9b63943d533?source=cve","https://plugins.trac.wordpress.org/browser/ultimate-flipbox-addon-for-elementor/tags/2.1.1/widget/simple/ufae-frontend/class-ufae-frontend-item.php#L250","https://plugins.trac.wordpress.org/browser/ultimate-flipbox-addon-for-elementor/tags/2.1.1/widget/stories/ufae-frontend/class-ufae-frontend-loop.php#L248","https://plugins.trac.wordpress.org/browser/ultimate-flipbox-addon-for-elementor/tags/2.1.2/widget/simple/ufae-frontend/class-ufae-frontend-item.php#L263","https://plugins.trac.wordpress.org/browser/ultimate-flipbox-addon-for-elementor/tags/2.1.2/widget/stories/ufae-frontend/class-ufae-frontend-loop.php#L253"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:12:49.727Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/6xxx/CVE-2026-6048.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-6048","state":"PUBLISHED","datePublished":"2026-04-18T03:37:05.751Z","dateUpdated":"2026-04-20T13:46:08.081Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-04-09T19:32:35.200Z"},"containers":{"cna":{"title":"Flipbox Addon for Elementor <= 2.1.1 - Authenticated (Author+) Stored Cross-Site Scripting via Custom Attributes","descriptions":[{"lang":"en","value":"The Flipbox Addon for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Flipbox widget's button URL `custom_attributes` field in all versions up to, and including, 2.1.1 due to insufficient validation of custom attribute names.
