Input validation vulnerability in Slider Revolution 6.6.19

The Slider Revolution plugin for WordPress has a security issue that could allow attackers to inject harmful code into the system. This vulnerability exists in all versions up to 6.6.19 and can be exploited when a new slider is imported using untrusted input. However, this can only be done by authenticated attackers with author-level access or higher. If there is a secondary plugin or theme installed on the system with a POP chain, the attacker could potentially delete files, access sensitive information, or run code.
