{"id":"CVE-2026-3011","state":"PUBLISHED","title":"Recipe Card Blocks Lite <= 3.4.13 - Authenticated (Author+) Stored Cross-Site Scripting via 'summary' and 'notes'","description":"The Recipe Card Blocks Lite plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the recipe block's 'summary' and 'notes' attributes in all versions up to, and including, 3.4.13. This is due to the 'WPZOOM_Helpers::deserialize_block_attributes' method converting unicode-encoded sequences back into HTML characters after sanitization has already been applied. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that execute whenever a user accesses the published post or the print view of an injected recipe.","publishedAt":"2026-06-08T11:23:49.193Z","updatedAt":"2026-06-08T16:22:10.202Z","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":["wpzoom Recipe Card Blocks Lite"],"affected":[{"vendor":"wpzoom","product":"Recipe Card Blocks Lite","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.4.13","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/a684bf5f-7cf6-43b1-b457-fdc2ba74852d?source=cve","https://plugins.trac.wordpress.org/browser/recipe-card-blocks-by-wpzoom/trunk/src/classes/class-wpzoom-print-template-manager.php#L224","https://plugins.trac.wordpress.org/browser/recipe-card-blocks-by-wpzoom/trunk/src/classes/class-wpzoom-helpers.php#L253","https://plugins.trac.wordpress.org/browser/recipe-card-blocks-by-wpzoom/trunk/src/structured-data-blocks/class-wpzoom-recipe-card-block.php#L582","https://plugins.trac.wordpress.org/browser/recipe-card-blocks-by-wpzoom/trunk/src/structured-data-blocks/class-wpzoom-recipe-card-block.php#L592","https://plugins.trac.wordpress.org/changeset/3470036/"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:11:50.837Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/3xxx/CVE-2026-3011.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-3011","state":"PUBLISHED","datePublished":"2026-06-08T11:23:49.193Z","dateUpdated":"2026-06-08T16:22:10.202Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-02-23T06:37:12.178Z"},"containers":{"cna":{"title":"Recipe Card Blocks Lite <= 3.4.13 - Authenticated (Author+) Stored Cross-Site Scripting via 'summary' and 'notes'","descriptions":[{"lang":"en","value":"The Recipe Card Blocks Lite plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the recipe block's 'summary' and 'notes' attributes in all versions up to, and including, 3.4.13.
