{"cve":"CVE-2026-3649","nvd":{"published":"2026-04-15T09:16:31.917","modified":"2026-06-17T10:43:55.263","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-862"],"references":["https://plugins.trac.wordpress.org/browser/katalogportal-pdf-sync/tags/1.0.0/inc/class.admin.php#L12","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/trunk/inc/class.admin.php#L209","https://www.wordfence.com/threat-intel/vulnerabilities/id/a01e7b21-f3ff-42a8-b78a-ad69973eda01?source=cve"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:30:49.762551342+00:00"},"epss":{"cve":"CVE-2026-3649","score":0.00316,"percentile":0.24539,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
