En ouvrant votre back office de WordPress, peut être avait vous remarqué qu’une mise à jour était disponible. Il s’agit de la version 4.8.2 de WordPress. Elle corrige un certains nombres de soucis de sécurité de la version prcédente.

Voici la liste (en anglais) des corrections de cette version :

  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).

Bien évidemment on vous conseille ardemment de faire cette mise à jour en pensant bien sûr à faire des sauvegardes avant de la lancer. Ceux qui ont réglé les MAJ de WordPress en automatique non pas besoin de la lancer en manuel.
