This is due to insufficient input sanitization and output escaping on user supplied attributes (`unset`, `before`, `after`). 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.","publishedAt":"2026-03-26T04:28:48.801Z","updatedAt":"2026-04-08T17:28:35.417Z","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":["hupe13 DSGVO snippet for Leaflet Map and its Extensions"],"affected":[{"vendor":"hupe13","product":"DSGVO snippet for Leaflet Map and its Extensions","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.1","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/dfeaff92-165a-4006-8e52-a99ae6b68dd9?source=cve","https://plugins.trac.wordpress.org/browser/dsgvo-leaflet-map/trunk/php/time-delete.php#L35","https://plugins.trac.wordpress.org/browser/dsgvo-leaflet-map/tags/3.1/php/time-delete.php#L35","https://plugins.trac.wordpress.org/browser/dsgvo-leaflet-map/tags/3.4","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=3489426%40dsgvo-leaflet-map%2Ftrunk&old=3488424%40dsgvo-leaflet-map%2Ftrunk&sfp_email=&sfph_mail="],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/4xxx/CVE-2026-4389.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-4389","state":"PUBLISHED","datePublished":"2026-03-26T04:28:48.801Z","dateUpdated":"2026-04-08T17:28:35.417Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-18T15:02:10.514Z"},"containers":{"cna":{"title":"DSGVO snippet for Leaflet Map and its Extensions <= 3.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'unset' Attribute","descriptions":[{"lang":"en","value":"The DSGVO snippet for Leaflet Map and its Extensions plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `leafext-cookie-time` and `leafext-delete-cookie` shortcodes in all versions up to, and including, 3.1.
