Page Builder: Live Composer < 1.5.29 - Author+ PHP Object Injection

Description The plugin is vulnerable to PHP Object Injection via deserialization of untrusted input. This makes it possible for authenticated attackers, with author-level access and above, to inject a PHP Object. No POP chain is present in the vulnerable plugin. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
