Output validation vulnerability in Blog2Social: Social Media Auto Post & Scheduler 5.0.1

The Blog2Social: Social Media Auto Post & Scheduler WordPress plugin is vulnerable to a security issue called PHP Object Injection in versions up to 5.0.0. This means that if an attacker is authenticated, they can inject a PHP Object. This could allow them to delete files, access sensitive data, or execute code. There is no chain of vulnerabilities present in the vulnerable plugin, but if a chain is present due to an additional plugin or theme installed on the system, then the attacker may be able to use it to their advantage.
