{"id":"CVE-2026-12407","state":"PUBLISHED","title":"E2Pdf <= 1.32.26 - Missing Authorization to Authenticated (Custom+) Arbitrary Option Update / Privilege Escalation via 'screen_action' Parameter","description":"The E2Pdf – Export Pdf Tool for WordPress plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 1.32.26. This is due to the screen_action() function lacking a dedicated capability check and nonce verification — when invoked via the ?action=screen routing path the controller's index_action() nonce gate is bypassed entirely — while reading an attacker-controlled option name and value from $_POST['wp_screen_options'] and passing them directly to update_option() with no allowlist, relying solely on the page-level e2pdf_templates capability which the plugin's own Permissions UI allows administrators to grant to any role including Subscriber, Contributor, Author, or Editor. This makes it possible for authenticated attackers, with a custom role that has been granted the e2pdf_templates capability, to overwrite arbitrary WordPress options such as default_role and thereby escalate their privileges to administrator.","publishedAt":"2026-06-18T03:41:39.487Z","updatedAt":"2026-06-18T12:46:32.925Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["oleksandrz E2Pdf – Export Pdf Tool for WordPress"],"affected":[{"vendor":"oleksandrz","product":"E2Pdf – Export Pdf Tool for WordPress","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.32.26","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/ee4c5d34-74cb-443b-9323-90580dbe675e?source=cve","https://plugins.trac.wordpress.org/browser/e2pdf/tags/1.32.26/classes/controller/e2pdf-templates.php#L1235","https://plugins.trac.wordpress.org/browser/e2pdf/tags/1.32.26/classes/controller/e2pdf-templates.php#L1233","https://plugins.trac.wordpress.org/browser/e2pdf/tags/1.32.26/classes/helper/e2pdf-view.php#L90","https://plugins.trac.wordpress.org/browser/e2pdf/tags/1.32.26/classes/controller/e2pdf-templates.php#L23","https://plugins.trac.wordpress.org/browser/e2pdf/tags/1.32.11/classes/controller/e2pdf-templates.php#L1235","https://plugins.trac.wordpress.org/browser/e2pdf/tags/1.32.11/classes/controller/e2pdf-templates.php#L1233","https://plugins.trac.wordpress.org/browser/e2pdf/tags/1.32.11/classes/helper/e2pdf-view.php#L90","https://plugins.trac.wordpress.org/browser/e2pdf/tags/1.32.11/classes/controller/e2pdf-templates.php#L23","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3574750%40e2pdf&new=3574750%40e2pdf&sfp_email=&sfph_mail="],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:10:52.580Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/12xxx/CVE-2026-12407.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-12407","state":"PUBLISHED","datePublished":"2026-06-18T03:41:39.487Z","dateUpdated":"2026-06-18T12:46:32.925Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-06-16T14:20:41.938Z"},"containers":{"cna":{"title":"E2Pdf <= 1.32.26 - Missing Authorization to Authenticated (Custom+) Arbitrary Option Update / Privilege Escalation via 'screen_action' Parameter","descriptions":[{"lang":"en","value":"The E2Pdf – Export Pdf Tool for WordPress plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 1.32.26.
