attackers to inject arbitrary web script or HTML via the name or
version header of a plugin.

CVE-2017-5489

Cross-site request forgery (CSRF) vulnerability in WordPress before
4.7.1 allows remote attackers to hijack the authentication of
unspecified victims via vectors involving a Flash file upload.

CVE-2017-5490

Cross-site scripting (XSS) vulnerability in the theme-name fallback
functionality in wp-includes/class-wp-theme.php in WordPress before
4.7.1 allows remote attackers to inject arbitrary web script or HTML
via a crafted directory name of a theme, related to
wp-admin/includes/class-theme-installer-skin.php.

CVE-2017-5491

wp-mail.php in WordPress before 4.7.1 might allow remote attackers to
bypass intended posting restrictions via a spoofed mail server with the

accessibility-mode feature in WordPress before 4.7.1 allows remote

CVE-2017-5493

before 4.7.1 does not properly choose random numbers for keys, which
makes it easier for remote attackers to bypass intended access
restrictions via a crafted site signup or user signup.

CVE-2017-5610

wp-admin/includes/class-wp-press-this.php in Press This in WordPress
before 4.7.2 does not properly restrict visibility of a
taxonomy-assignment user interface, which allows remote attackers to
bypass intended access restrictions by reading terms.

CVE-2017-5611

SQL injection vulnerability in wp-includes/class-wp-query.php in
WP_Query in WordPress before 4.7.2 allows remote attackers to execute
arbitrary SQL commands by leveraging the presence of an affected
plugin or theme that mishandles a crafted post type name.

CVE-2017-5612

Cross-site scripting (XSS) vulnerability in
wp-admin/includes/class-wp-posts-list-table.php in the posts list
table in WordPress before 4.7.2 allows remote attackers to inject
