CVE-2026-12407

What is known

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.

Business impact

Successful exploitation of CVE-2026-12407, a high vulnerability (CVSS 8.8) affecting the affected product, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.

Recommended administrator action

Confirm whether the affected product is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
