Vulnerability Discovered in Facebook WordPress Plugin

Multiple vulnerabilities were recently discovered in Facebook for WordPress, formerly known as Official Facebook Pixel, a WordPress plugin installed on over 500,000 sites. This flaw made it possible for unauthenticated attackers with access to a site’s secret salts and keys to achieve remote code execution through a deserialization weakness.

These are considered high and critical severity vulnerabilities. Therefore, we highly recommend updating to the latest version available containing both patches, 3.0.5, immediately.
