Input validation vulnerability in E2Pdf – Export To Pdf Tool for WordPress 1.20.20

The E2Pdf – Export To Pdf Tool for WordPress plugin is vulnerable to a security issue if it is used with a WordPress website and the version is up to 1.20.20 (but not past that version). It is possible for people with access to the administrator setting to inject malicious code into pages on a website. This code could be used to run malicious scripts when someone visits those pages. This security issue only affects websites that are setup as multi-site installations or have disabled the ‘unfiltered_html’ setting.
