CVE-2023-6826: e2pdf vulnerability

What is known

The E2Pdf plugin for WordPress is vulnerable to arbitrary file uploads due to insufficient file type validation on the 'import_action' function in versions up to, and including, 1.20.25. This makes it possible for authenticated attackers with a role that the administrator previously granted access to the plugin, to upload arbitrary files on the affected site's server which may make remote code execution possible.

Business impact

Successful exploitation of CVE-2023-6826, a high vulnerability (CVSS 7.2) affecting e2pdf, 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 e2pdf 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.
