{"id":"CVE-2026-109975","published":"2026-10-28T07:16:45.163","lastModified":"2026-10-28T07:16:45.163","description":"The Cozy Blocks – Website Builder for WordPress Block Editor | Gutenberg Blocks, Patterns & Templates plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'content (block attribute icon.view / icon.layout / icon.gap)' parameter in all versions up to, and including, 2.2.27 due to insufficient input sanitization and output 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. Although wp_kses_post is applied on save, it does not neutralize a quote-only attribute-breakout payload containing no '<' character, leaving the block comment and its decoded JSON attributes intact and exploitable at render time.","cvssScore":6.4,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://plugins.trac.wordpress.org/browser/cozy-addons/tags/2.2.27/blocks/featured-product-tabs/block.json#L777","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/cozy-addons/tags/2.2.27/blocks/featured-product-tabs/render.php#L927","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/cozy-addons/tags/2.2.27/blocks/featured-product-tabs/render.php#L929","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/cozy-addons/tags/2.2.27/blocks/featured-product-tabs/render.php#L935","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/cozy-addons/tags/2.2.27/blocks/featured-product-tabs/render.php#L943","tags":[]},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3752142%40cozy-addons&new=3752142%40cozy-addons","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/f4041795-8131-459f-9156-5ecf5d6086f6?source=cve","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
