What are nonce validations, and why are they important?

Nonce validations are security tokens used by WordPress to verify that an action or request received by a website comes from a legitimate source, typically to protect against CSRF attacks. Nonces are unique to each session and action, making it difficult for attackers to forge a valid request.
