WordPress Content Egg Plugin PHP Object Injection Vulnerability

A deserialization vulnerability allowing object injection has been identified in the WordPress Content Egg plugin, affecting versions through 7.0.0. This vulnerability arises from the deserialization of untrusted data, which could potentially be exploited to execute arbitrary code, inject malicious SQL, traverse directories in an unintended manner, cause a denial-of-service, or more, if a suitable property-oriented programming chain is available.

Impact

Exploitation of this vulnerability could lead to PHP object injection, allowing for a range of attacks including code execution, SQL injection, path traversal, and denial-of-service, depending on the presence of a proper object injection chain.

Remediation

Users of the WordPress Content Egg plugin should update to version 8.0.0 or later. Patchstack users can enable auto-updates for vulnerable plugins.
