Name of the Vulnerable Software and Affected Versions E2Pdf plugin for WordPress versions up to, and including, 1.20.25

Description The issue arises from insufficient file type validation on the import action function, allowing authenticated attackers with granted access to the plugin to upload arbitrary files on the site's server, potentially enabling remote code execution.

Recommendations For versions up to, and including, 1.20.25, consider disabling the import action function until a patch is available to prevent arbitrary file uploads. Restrict access to the E2Pdf plugin to minimize the risk of exploitation. Avoid using the E2Pdf plugin for file imports until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
