Details from the advisory

The Lightweight Cookie Notice – Cookie Banner for Cookie Consent plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.19 This is due to the W3TC_DYNAMIC_SECURITY constant being hardcoded to a publicly known value. This makes it possible for unauthenticated attackers to know the W3 Total Cache mfunc security key, which when W3 Total Cache is installed may allow arbitrary PHP code injection.
