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."}],"title":"Shariff Wrapper <= 4.6.20 - Authenticated (Contributor+) Cross-Site Scripting","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/e037d22a-3d4d-4f70-a749-6d6c552c7553?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/shariff/trunk/shariff.php#L1143"},{"url":"https://plugins.trac.wordpress.org/browser/shariff/trunk/shariff.php#L1144"},{"url":"https://plugins.trac.wordpress.org/browser/shariff/trunk/shariff.php#L965"},{"url":"https://plugins.trac.wordpress.org/browser/shariff/trunk/shariff.php#L868"},{"url":"https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3532532%40shariff&new=3532532%40shariff&sfp_email=&sfph_mail="}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')","cweId":"CWE-79","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"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"}}],"credits":[{"lang":"en","type":"finder","value":"Muhammad Yudha - DJ"}],"timeline":[{"time":"2026-04-17T06:27:54.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-05-27T19:48:38.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-05-28T10:09:43.921367Z","id":"CVE-2026-4334","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-05-28T10:31:28.554Z"}}]}}
