E2Pdf <= 1.32.26 — Missing Authorization to Authenticated (Custom+) Arbitrary Option Update / Privilege Escalation via 'screen_action' Parameter

Am I affected?

• Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under E2Pdf – Export Pdf Tool for WordPress.
• No admin access? Run a passive check of your site. It reads public files only.

What to do

1. Update to version 1.32.31, or a newer patched version
2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
3. Watch E2Pdf – Export Pdf Tool for WordPress to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to endy.

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.
