Input validation vulnerability in Noisa 2.6.0

The Noisa theme for WordPress has a security issue where untrusted information can be used to inject a PHP Object. This can be done by attackers who have at least subscriber-level access to the system. It is important to note that this vulnerability does not currently have a known way for attackers to take advantage of it, but if a certain type of additional software is installed, it could potentially allow the attacker to perform harmful actions like deleting files, accessing private information, or running code.
