WordPress before 4.4 makes it easier for remote attackers to predict password-recovery tokens via a brute-force approach.

SQL injection vulnerability in ajax_comments.php in the WP Comment Remix plugin before 1.4.4 for WordPress allows remote attackers to execute arbitrary SQL commands via the p parameter.

Multiple cross-site scripting (XSS) vulnerabilities in wp-login.php in the Register Plus plugin 3.5.1 and earlier for WordPress allow remote attackers to inject arbitrary web script or HTML via the (1) firstname, (2) lastname, (3) website, (4) aim, (5) yahoo, (6) jabber, (7) about, (8) pass1, and (9) pass2 parameters in a register action.

WordPress before 5.1.1 does not properly filter comment content, leading to Remote Code Execution by unauthenticated users in a default configuration. This occurs because CSRF protection is mishandled, and because Search Engine Optimization of A elements is performed incorrectly, leading to XSS. The XSS results in administrative access, which allows arbitrary changes to .php files. This is related to wp-admin/includes/ajax-actions.php and wp-includes/comment.php.

Cross-site scripting (XSS) vulnerability in edit-post.php in the Flexible Custom Post Type plugin before 0.1.7 for WordPress allows remote attackers to inject arbitrary web script or HTML via the id parameter.

In WordPress before 4.9.9 and 5.x before 5.0.1, contributors could modify new comments made by users with greater privileges, possibly causing XSS.

Cross-site scripting (XSS) vulnerability in clickdesk.php in ClickDesk Live Support - Live Chat plugin 2.0 for WordPress allows remote attackers to inject arbitrary web script or HTML via the cdwidgetid parameter. NOTE: some of these details are obtained from third party information.

Cross-site request forgery (CSRF) vulnerability in askapache-firefox-adsense.php in the AskApache Firefox Adsense plugin 3.0 and earlier for WordPress allows remote attackers to hijack the authentication of administrators for requests that conduct cross-site scripting (XSS) attacks via the aafireadcode parameter to wp-admin/options-general.php.

wp-admin/user-new.php in WordPress before 4.9.1 sets the newbloguser key to a string that can be directly derived from the user ID, which allows remote attackers to bypass intended access restrictions by entering this string.

WordPress through 5.0.3 allows Path Traversal in wp_crop_image(). An attacker (who has privileges to crop an image) can write the output image to an arbitrary directory via a filename containing two image extensions and ../ sequences, such as a filename ending with the .jpg?/../../file.jpg substring.
