{"cve":"CVE-2026-109975","nvd":{"published":"2026-10-28T07:16:45.163","modified":"2026-10-28T07:16:45.163","status":"Received","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":6.4},"cwes":["CWE-79"],"references":["https://plugins.trac.wordpress.org/browser/cozy-addons/tags/2.2.27/blocks/featured-product-tabs/block.json#L777","https://plugins.trac.wordpress.org/browser/cozy-addons/tags/2.2.27/blocks/featured-product-tabs/render.php#L927","https://plugins.trac.wordpress.org/browser/cozy-addons/tags/2.2.27/blocks/featured-product-tabs/render.php#L929","https://plugins.trac.wordpress.org/browser/cozy-addons/tags/2.2.27/blocks/featured-product-tabs/render.php#L935","https://plugins.trac.wordpress.org/browser/cozy-addons/tags/2.2.27/blocks/featured-product-tabs/render.php#L943"],"products":[],"source":"nvd","synced_at":"2026-10-28T07:37:43.411221249+00:00"},"epss":null,"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
