CVE-2022-4324

Name of the Vulnerable Software and Affected Versions Custom Field Template WordPress plugin versions prior to 2.5.8

Description The issue arises from the unserialization of the content of an imported file, potentially leading to PHP object injections when a high-privilege user imports a malicious Customizer Styling file and a suitable gadget chain is present on the blog.

Recommendations For versions prior to 2.5.8, update to version 2.5.8 or later to resolve the issue. As a temporary workaround, consider restricting the import of Customizer Styling files to trusted sources and users until the update is applied.
