The maintenance aspect of the latest release includes six software updates. However, the general focus this time has been on the following:

This security and maintenance release includes a fix to $wpdb->prepare(). This will prevent the WordPress website users from any SQL injection attacks. Although it is a fact that the core WordPress content management system is prone to any kind of SQL injection attacks.

But the same cannot be said for some of the plugins, extensions, and themes which a user may add onto his website. This depends on how an admin of a WordPress website may use the $wpdb->prepare() function in their syntax.

The cross site vulnerability, which was the major reason behind this security and maintenance release, were found in the following:

  • Template names
  • oEmbed discovery
  • Plugin editor
  • Visual editor

Such cross-site vulnerabilities are one of the popular vulnerabilities found in WordPress plugins and themes.

Also known as XSS, cross site scripting is a way of bypassing the SOP. Whenever HTML code is generated and the user input is reflected on the page, any intruder or malicious source can easily add his own HTML code or javascript code which would run under the context of the WordPress website. This is generally done by hackers to access other pages on the same domain and get access to confidential data or cookies.

Apart from the cross site vulnerability, WordPress also fixed 2 path traversal vulnerabilities. These were found in the following locations:

  • Customizer
  • File unzipping
