{"id":"CVE-2026-4334","state":"PUBLISHED","title":"Shariff Wrapper <= 4.6.20 - Authenticated (Contributor+) Cross-Site Scripting","description":"The Shariff Wrapper plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'headline' parameter in the [shariff] shortcode in all versions up to, and including, 4.6.20 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. The vulnerability occurs because the plugin uses a custom wp_kses implementation with permissive allowed HTML tags, and then performs a str_replace operation that injects HTML after sanitization, allowing event handlers to be introduced through the %total placeholder in the style attribute.","publishedAt":"2026-05-28T08:27:38.853Z","updatedAt":"2026-05-28T10:31:28.554Z","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":["3uu Shariff Wrapper"],"affected":[{"vendor":"3uu","product":"Shariff Wrapper","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"4.6.20","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/e037d22a-3d4d-4f70-a749-6d6c552c7553?source=cve","https://plugins.trac.wordpress.org/browser/shariff/trunk/shariff.php#L1143","https://plugins.trac.wordpress.org/browser/shariff/trunk/shariff.php#L1144","https://plugins.trac.wordpress.org/browser/shariff/trunk/shariff.php#L965","https://plugins.trac.wordpress.org/browser/shariff/trunk/shariff.php#L868","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3532532%40shariff&new=3532532%40shariff&sfp_email=&sfph_mail="],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/4xxx/CVE-2026-4334.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-4334","state":"PUBLISHED","datePublished":"2026-05-28T08:27:38.853Z","dateUpdated":"2026-05-28T10:31:28.554Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-17T14:11:01.203Z"},"containers":{"cna":{"title":"Shariff Wrapper <= 4.6.20 - Authenticated (Contributor+) Cross-Site Scripting","descriptions":[{"lang":"en","value":"The Shariff Wrapper plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'headline' parameter in the [shariff] shortcode in all versions up to, and including, 4.6.20 due to insufficient input sanitization and output escaping.
