{"identifier":"CVE-2026-109975","cve":{"id":"CVE-2026-109975","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.","published":"2026-10-28T07:16:45.163000+00:00","modified":"2026-10-29T02:16:47.467000+00:00","status":"Deferred","score":6.4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","cvss_version":"3.1","affected":[],"weaknesses":["CWE-79"],"references":[{"url":"https://plugins.trac.wordpress.org/browser/cozy-addons/tags/2.2.27/blocks/featured-product-tabs/block.json#L777","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/cozy-addons/tags/2.2.27/blocks/featured-product-tabs/render.php#L927","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/cozy-addons/tags/2.2.27/blocks/featured-product-tabs/render.php#L929","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/cozy-addons/tags/2.2.27/blocks/featured-product-tabs/render.php#L935","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/cozy-addons/tags/2.2.27/blocks/featured-product-tabs/render.php#L943","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3752142%40cozy-addons&new=3752142%40cozy-addons","source":"security@wordfence.com"},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/f4041795-8131-459f-9156-5ecf5d6086f6?source=cve","source":"security@wordfence.com"}],"kev":null,"kev_checked":true,"metrics":{"cvssMetricV31":[{"source":"security@wordfence.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","baseScore":6.4,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"LOW","integrityImpact":"LOW","availabilityImpact":"NONE"},"exploitabilityScore":3.1,"impactScore":2.7}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-29T01:28:50.750954Z","id":"CVE-2026-109975","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"configurations":[],"source":"nvd","retrieved_at":"2026-10-29T05:29:54.776378+00:00","exploited":false,"kev_stale":false,"products":[],"priority":{"label":"Assess exposure and vendor guidance","reasons":["No higher-priority signal is available in the current stored evidence."]},"epss":{"probability":0.00201,"percentile":0.09955,"date":"2026-10-28","stale":false},"version_assessment":null},"news":[],"campaigns":[],"domains":[{"domain":"plugins.trac.wordpress.org","source_url":"https://plugins.trac.wordpress.org/browser/cozy-addons/tags/2.2.27/blocks/featured-product-tabs/block.json#L777","investigate_url":"https://investigate.aeglixmind.com/#plugins.trac.wordpress.org"},{"domain":"www.wordfence.com","source_url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/f4041795-8131-459f-9156-5ecf5d6086f6?source=cve","investigate_url":"https://investigate.aeglixmind.com/#www.wordfence.com"}],"arsenal_url":"https://arsenal.aeglixmind.com/?cve=CVE-2026-109975","catalog_url":"https://cves.aeglixmind.com/cve/CVE-2026-109975","research_url":"https://investigate.aeglixmind.com/research/cve/CVE-2026-109975","coverage":{"news_candidates_checked":0,"campaign_candidates_checked":0,"bounded":false,"notice":"Exact CVE mentions in stored public excerpts and reviewed campaign content only.
