Description

The ACF Frontend Admin by DynamiApps WordPress plugin through 3.29.13 does not restrict which PHP classes may be instantiated when it deserialises stored post content that is rendered on public-facing pages, allowing high-privilege users such as administrators to inject a PHP object which, given a suitable POP chain in another installed ACF Frontend Admin by DynamiApps WordPress plugin through 3.29.13 or in WordPress core, can be leveraged to achieve remote code execution.
