[SECURITY-L] WordPress 4.8.2 Security and Maintenance Release

[CSIRT Unicamp]

WordPress 4.8.2 is now available. This is a security release for all
previous versions and we strongly encourage you to update your sites
immediately.

WordPress versions 4.8.1 and earlier are affected by these security
issues:

 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).
Thank you to the reporters of these issues for practicing responsible
disclosure.

In addition to the security issues above, WordPress 4.8.2 contains 6
maintenance fixes to the 4.8 release series. For more information, see
