{"id":"CVE-2026-5428","state":"PUBLISHED","title":"Royal Addons for Elementor <= 1.7.1056 - Authenticated (Author+) Stored Cross-Site Scripting via Image Caption Field","description":"The Royal Elementor Addons plugin for WordPress is vulnerable to Stored Cross-Site Scripting via image captions in the Image Grid/Slider/Carousel widget in versions up to and including 1.7.1056. This is due to insufficient output escaping in the render_post_thumbnail() function, where wp_kses_post() is used instead of esc_attr() for the alt attribute context. 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 a page with the malicious image displayed in the media grid widget.","publishedAt":"2026-04-24T05:29:38.884Z","updatedAt":"2026-08-14T19:07:49.583Z","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":["wproyal Royal Addons for Elementor – Addons and Templates Kit for Elementor"],"affected":[{"vendor":"wproyal","product":"Royal Addons for Elementor – Addons and Templates Kit for Elementor","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.7.1056","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/ba7b8fe5-aa49-4a70-89c9-1b95a30b1142?source=cve","https://plugins.trac.wordpress.org/browser/royal-elementor-addons/trunk/modules/media-grid/widgets/wpr-media-grid.php#L6755","https://plugins.trac.wordpress.org/browser/royal-elementor-addons/tags/1.7.1049/modules/media-grid/widgets/wpr-media-grid.php#L6755","https://plugins.trac.wordpress.org/browser/royal-elementor-addons/trunk/modules/media-grid/widgets/wpr-media-grid.php#L6752","https://plugins.trac.wordpress.org/browser/royal-elementor-addons/tags/1.7.1049/modules/media-grid/widgets/wpr-media-grid.php#L6752","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3503209%40royal-elementor-addons&new=3503209%40royal-elementor-addons&sfp_email=&sfph_mail=","https://research.cleantalk.org/cve-2026-5428"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:12:32.778Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/5xxx/CVE-2026-5428.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-5428","state":"PUBLISHED","datePublished":"2026-04-24T05:29:38.884Z","dateUpdated":"2026-08-14T19:07:49.583Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-04-02T14:30:44.825Z"},"containers":{"cna":{"title":"Royal Addons for Elementor <= 1.7.1056 - Authenticated (Author+) Stored Cross-Site Scripting via Image Caption Field","descriptions":[{"lang":"en","value":"The Royal Elementor Addons plugin for WordPress is vulnerable to Stored Cross-Site Scripting via image captions in the Image Grid/Slider/Carousel widget in versions up to and including 1.7.1056.
