{"id":"CVE-2026-3649","state":"PUBLISHED","title":"Katalogportal-pdf-sync Widget <= 1.0.0 - Missing Authorization to Authenticated (Subscriber+) Information Disclosure via 'katalogportal_shortcodePrinter' AJAX Action","description":"The Katalogportal PDF Sync plugin for WordPress is vulnerable to Missing Authorization in all versions up to and including 1.0.0. The katalogportal_popup_shortcode() function is registered as an AJAX handler via wp_ajax_katalogportal_shortcodePrinter but lacks any capability check (current_user_can()) or nonce verification. This allows any authenticated user, including Subscribers, to call the endpoint and retrieve a list of all synchronized PDF attachments (including those attached to private or draft posts) along with their titles, actual filenames, and the katalogportal_userid configuration value. The WP_Query uses post_status => 'any' which returns attachments regardless of the parent post's visibility status.","publishedAt":"2026-04-15T08:28:15.977Z","updatedAt":"2026-04-15T15:42:28.267Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["colbeinformatik Katalogportal-pdf-sync Widget"],"affected":[{"vendor":"colbeinformatik","product":"Katalogportal-pdf-sync Widget","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.0.0","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/a01e7b21-f3ff-42a8-b78a-ad69973eda01?source=cve","https://plugins.trac.wordpress.org/browser/katalogportal-pdf-sync/trunk/inc/class.admin.php#L209","https://plugins.trac.wordpress.org/browser/katalogportal-pdf-sync/tags/1.0.0/inc/class.admin.php#L209","https://plugins.trac.wordpress.org/browser/katalogportal-pdf-sync/trunk/inc/class.admin.php#L12","https://plugins.trac.wordpress.org/browser/katalogportal-pdf-sync/tags/1.0.0/inc/class.admin.php#L12"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:11:50.837Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/3xxx/CVE-2026-3649.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-3649","state":"PUBLISHED","datePublished":"2026-04-15T08:28:15.977Z","dateUpdated":"2026-04-15T15:42:28.267Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-06T16:23:45.982Z"},"containers":{"cna":{"title":"Katalogportal-pdf-sync Widget <= 1.0.0 - Missing Authorization to Authenticated (Subscriber+) Information Disclosure via 'katalogportal_shortcodePrinter' AJAX Action","descriptions":[{"lang":"en","value":"The Katalogportal PDF Sync plugin for WordPress is vulnerable to Missing Authorization in all versions up to and including 1.0.0.
