WordPress regularly provides new versions with new features, improvements of existing features, and bug fixes. The sites with old WordPress versions are prone to more security threats than the sites with the latest WordPress version. Due to its open source nature and huge community, security issues in WordPress versions tend to get public very quickly. Therefore, attackers can easily use these vulnerabilities to create threats in various ways. Once an issue is identified, WordPress fixes it very quickly by releasing a new version. So, it's important to upgrade the WordPress version as soon as possible to prevent security threats.
