Security Changes in WordPress 4.8.2

WordPress has made nine security changes in its latest release.

WordPress 4.8.2 is out and it has undergone nine security changes for its latest iteration. WordPress strongly encourages its users to make the update as soon as possible given several of the security risks that have been discovered.

Here’s what was fixed in 4.8.2:

  1. $wpdb->prepare() can create unexpected and unsafe queries leading to potential SQL injection (SQLi). WordPress core is not directly vulnerable to this issue, but we’ve added hardening to prevent plugins and themes from accidentally causing a vulnerability. Reported by Slavco

  2. A cross-site scripting (XSS) vulnerability was discovered in the oEmbed discovery. Reported by xknown of the WordPress Security Team.

  3. A cross-site scripting (XSS) vulnerability was discovered in the visual editor. Reported by Rodolfo Assis (@brutelogic) of Sucuri Security.

  4. A path traversal vulnerability was discovered in the file unzipping code. Reported by Alex Chapman (noxrnet).

  5. A cross-site scripting (XSS) vulnerability was discovered in the plugin editor. Reported by 陈瑞琦 (Chen Ruiqi).

  6. An open redirect was discovered on the user and term edit screens. Reported by Yasin Soliman (ysx).

  7. A path traversal vulnerability was discovered in the customizer. Reported by Weston Ruter of the WordPress Security Team.

  8. A cross-site scripting (XSS) vulnerability was discovered in template names. Reported by Luka (sikic).

  9. A cross-site scripting (XSS) vulnerability was discovered in the link modal. Reported by Anas Roubi (qasuar).

WordPress also thanked the individuals that reported the vulnerabilities for practicing responsible disclosure. Responsible disclosure is when a vulnerability isn’t made public until the company behind the program, system or software has an opportunity to patch it.

You can download the new version of WordPress in your dashboard. Again, WordPress recommends that you do this immediately to shore up your cyber defenses. As Equifax found out the hard way, waiting to make critical updates can cost you big time.
