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. Because the data is stored via update_post_meta() rather than wp_insert_post() post content, WordPress's unfiltered_html restriction does not apply, meaning Authors cannot be blocked from this attack path by capability controls alone.","publishedAt":"2026-06-10T06:48:28.873Z","updatedAt":"2026-06-10T16:32:03.865Z","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":["brechtvds Easy Image Collage"],"affected":[{"vendor":"brechtvds","product":"Easy Image Collage","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.13.6","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/4feaad82-f94e-49f5-8e8b-67ba220b1c71?source=cve","https://plugins.trac.wordpress.org/browser/easy-image-collage/tags/1.13.6/helpers/shortcode.php#L42","https://plugins.trac.wordpress.org/browser/easy-image-collage/tags/1.13.6/helpers/layouts.php#L261","https://plugins.trac.wordpress.org/browser/easy-image-collage/tags/1.13.6/helpers/models/grid.php#L39","https://plugins.trac.wordpress.org/browser/easy-image-collage/tags/1.13.6/helpers/ajax.php#L16","https://plugins.trac.wordpress.org/changeset?old_path=easy-image-collage/tags/1.13.6&new_path=easy-image-collage/tags/2.0.0"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:13:52.441Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/9xxx/CVE-2026-9019.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-9019","state":"PUBLISHED","datePublished":"2026-06-10T06:48:28.873Z","dateUpdated":"2026-06-10T16:32:03.865Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-05-19T14:53:59.845Z"},"containers":{"cna":{"title":"Easy Image Collage <= 1.13.6 - Authenticated (Author+) Stored Cross-Site Scripting via 'grid[properties][borderColor]' and 'grid[images][N][attachment_url]' Parameters","descriptions":[{"lang":"en","value":"The Easy Image Collage plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'grid[properties][borderColor]' and 'grid[images][N][attachment_url]' Parameters in all versions up to, and including, 1.13.6 due to insufficient input sanitization and output escaping.
